Matcher

Tell it what you want. It answers with the whole ladder.

every row traces to a sectionno doses for unapproved compounds

A goal-to-compound lookup is the mechanic this document was written to take apart — it is what lets a rodent study and a Phase 3 trial look alike. So this one answers from the document's own ranked hierarchies in §15: strongest evidence first, the free interventions where the evidence actually puts them, and the compounds the category markets at the rank the document assigns them.

Type a goal, or pick one below. Pick two or more and it checks the stack.

§15 Pillar 1 — insulin resistance

Lose weight or body fat

This is the one area of the field with T1 evidence at scale, and it belongs to the incretins — not to the peptides the category markets. The document's own ranked hierarchy puts four free behavioural interventions above every drug, and puts MOTS-c and 5-Amino-1MQ at rank 8, rodent-only.

Ranked by evidence strength, strongest first

  1. 1 Energy balance and fat mass reduction, particularly visceral behaviour T1
  2. 2 Resistance training plus aerobic training behaviour T1
  3. 3 Sleep extension to 7–9 hours behaviour T1
  4. 4 Dietary quality: fibre, protein adequacy, alcohol reduction behaviour T1
  5. 5 Metformin drug T1
  6. 6 GLP-1 / GIP-GLP-1 agonists drug T1
  7. 7 Tesamorelin, for visceral fat, in its licensed population — T1 narrow drug T1
  8. 8 MOTS-c, 5-Amino-1MQ — rodent peptide T4
What the class actually does

Class-wide across GLP-1 and GIP/GLP-1: nausea, vomiting, diarrhoea, constipation; gallbladder disease and cholelithiasis; a pancreatitis signal; gastroparesis and delayed gastric emptying, which has produced anaesthesia aspiration guidance; a diabetic retinopathy progression signal with rapid HbA1c reduction; SUBSTANTIAL LOSS OF LEAN MASS alongside fat mass; and weight regain on discontinuation, demonstrated in the STEP 4 withdrawal design. §6

Do not use if

Personal or family history of medullary thyroid carcinoma or MEN2 — boxed contraindication. History of pancreatitis. Severe gastroparesis. Pregnancy. Type 1 diabetes. Caution with rapid HbA1c reduction in existing retinopathy. Anaesthesia planning required before elective procedures. §11

Measure first

Before an incretin, add lipase and amylase; calcitonin only if history warrants; document thyroid and family history. §11

Interactions

Incretins delay gastric emptying, altering absorption of oral medicines — narrow-therapeutic-index drugs need monitoring and warfarin INR should be checked more often. Combining with insulin or a sulfonylurea requires reducing that drug's dose or hypoglycaemia results. §11

Approved, and indicated for this

These have a label, a dose that is public prescribing information, and a regulator behind them.

§15 Pillar 1 — insulin resistance

Fix insulin resistance / metabolic health

Muscle contraction stimulates GLUT4 translocation through an insulin-INDEPENDENT, AMPK-linked pathway. That is why exercise improves glucose disposal in people whose insulin signalling is impaired, and it is the most robustly evidenced intervention available. Note too that the GH-axis compounds run the wrong way here: that whole class worsens insulin sensitivity.

Ranked by evidence strength, strongest first

  1. 1 Energy balance and fat mass reduction, particularly visceral behaviour T1
  2. 2 Resistance training plus aerobic training behaviour T1
  3. 3 Sleep extension to 7–9 hours behaviour T1
  4. 4 Dietary quality: fibre, protein adequacy, alcohol reduction behaviour T1
  5. 5 Metformin drug T1
  6. 6 GLP-1 / GIP-GLP-1 agonists drug T1
  7. 7 Tesamorelin, for visceral fat, in its licensed population — T1 narrow drug T1
  8. 8 MOTS-c, 5-Amino-1MQ — rodent peptide T4
What the class actually does

Everything on the GH axis — GHRH analogs, GHRPs, GH itself — worsens insulin sensitivity. Tesamorelin's own label carries glucose intolerance and new-onset diabetes. MK-677 consistently raises fasting glucose. For this specific goal those compounds are not neutral, they are counterproductive. §5, §11

Do not use if

Caution in any diabetes or prediabetes for the entire GH-axis class. §11

Measure first

Measurement for this goal: fasting glucose with fasting insulin computed as HOMA-IR; HbA1c; triglyceride-to-HDL ratio; ApoB; an oral glucose tolerance test with insulin if the picture is unclear. §15

§15 Pillar 2 — inflammation

Reduce chronic inflammation

'Chronic silent inflammation' is not a diagnosis and has no diagnostic criteria. hs-CRP is the practical marker with outcome data behind it. IL-6 is NOT a standard clinical monitoring assay — short-lived, highly variable, rises acutely with exercise — so building a protocol around serial IL-6 is measurement theatre. Every peptide marketed for this is T4, and the one intervention in this space that got a properly powered human trial missed its endpoint.

Ranked by evidence strength, strongest first

  1. 1 Energy balance and fat mass reduction, particularly visceral behaviour T1
  2. 2 Resistance training plus aerobic training behaviour T1
  3. 3 Sleep extension to 7–9 hours behaviour T1
  4. 4 Dietary quality: fibre, protein adequacy, alcohol reduction behaviour T1
  5. 5 Treatment of periodontal disease where present behaviour T1
  6. 6 Treatment of sleep apnoea where present behaviour T1
  7. 7 BPC-157, KPV, LL-37, SS-31 — the excerpt's anti-inflammatory protocol — for this purpose peptide T4
The document corrects this

Exercise-derived IL-6 is a MYOKINE with net anti-inflammatory downstream effects including induction of IL-10 and IL-1ra. Conflating it with adipose- and macrophage-derived chronic IL-6 leads to the wrong conclusion: suppressing a signal that is part of the adaptation. §15

What the class actually does

The excerpt's 'anti-inflammatory base protocol' — BPC-157 alone weeks 1-2, add SS-31 weeks 3-4, add MOTS-c weeks 5-8 — has no dose, no route and no frequency, and combines three compounds with no human efficacy data in a sequence that makes attribution impossible. It also places the first biomarker check at week 9 with no baseline, which makes that measurement uninterpretable. §15

Do not use if

Immune modulators: autoimmune disease, solid organ transplant, any immunosuppression. LL-37 specifically: psoriasis, rosacea, lupus. §11

Measure first

hs-CRP, with a baseline established first. §11, §15

Tested in humans, and failed

A compound with a failed adequately-powered trial has stronger evidence AGAINST it than one with no trial at all.

Cardiolipin-binding tetrapeptide. MMPOWER-3 MISSED ITS PRIMARY ENDPOINT. The Barth programme went through an FDA advisory committee with a narrow vote and subsequent regulatory back-and-forth.

THE SOURCE EXCERPT INVERTS THIS. LL-37 is a dual-function human cathelicidin: antimicrobial, but also strongly PRO-inflammatory in several contexts and mechanistically implicated in the pathology of psoriasis, rosacea and lupus, where it complexes with self-DNA to activate plasmacytoid dendritic cells and drive interferon responses. Using it as an anti-inflammatory is a genuine contraindication signal the source material reverses.

§15 Pillar 3 — sleep and the nocturnal axis

Sleep better

This is the pillar with the STRONGEST human evidence in the entire document, and it is the one the source product truncates. These are randomised or crossover human studies with effect sizes larger than anything demonstrated for any unapproved peptide here — and the intervention is free. Nothing in the peptide column competes.

Ranked by evidence strength, strongest first

  1. 1 Sleep opportunity — actually being in bed long enough behaviour T1
  2. 2 Timing regularity behaviour T1
  3. 3 Light exposure behaviour T1
  4. 4 Alcohol removal behaviour T1
  5. 5 Treatment of undiagnosed sleep apnoea behaviour T1
  6. 6 GHRH administration — modestly increases slow-wave sleep in research settings — not a licensed use peptide T3
  7. 7 DSIP — essentially no human evidence peptide T5
What the class actually does

Growth hormone secretion is concentrated in the first episodes of slow-wave sleep. Fragmenting or suppressing slow-wave sleep suppresses the nocturnal GH pulse directly — and NO SECRETAGOGUE RESTORES A PULSE THE ARCHITECTURE IS NOT THERE TO SUPPORT. If you are chasing GH, this is the upstream lever, not the peptide. §15

The human evidence, with effect sizes to verify
  • Restricting healthy young men to ~4 hours in bed for 6 nights produced a marked reduction in glucose tolerance and insulin sensitivity (Spiegel, Leproult & Van Cauter, Lancet 1999). Verify the exact effect size before quoting a percentage.
  • Restricting sleep to ~5 hours per night for one week reduced daytime testosterone by roughly 10–15% in healthy young men (Leproult & Van Cauter, JAMA 2011). Verify.
  • Sleep restriction during caloric restriction shifted the composition of weight lost AWAY from fat and toward lean mass (Nedeltcheva et al., Ann Intern Med 2010). Verify.

§7 — repair, regenerative and mitochondrial

Heal an injury — tendon, ligament, muscle

This is where the marketing is loudest and the evidence is thinnest. The two compounds that dominate this category are T4 — rodent — from largely single-group corpora, with NO published human pharmacokinetics, meaning even dosing frequency is guesswork. Both are on FDA's category 2 list, which is an affirmative safety finding rather than an absence of approval. Both are prohibited in tested sport.

Ranked by evidence strength, strongest first

  1. 1 Confirm the boring variables are fixed: sleep, protein adequacy, alcohol, programmed loading behaviour T1
  2. 2 Accept the biological floor — tissue repair is on the timescale of tissue repair, which no signalling molecule shortens — §14 principle 9 behaviour T1
  3. 3 BPC-157, TB-500 — rodent, no human PK peptide T4
What the class actually does

Both BPC-157 and TB-500 work through angiogenesis. The concern is promotion of occult malignancy or vascular lesions. It is mechanistic, not demonstrated — and it is also NOT EXCLUDED, because there is no long-term human safety data of any kind. Absence of data is not absence of risk. §7, §17

Do not use if

Any history of malignancy, and any undiagnosed lump, lesion or bleeding, until investigated. §11

Measure first

For anyone over 40 or with risk factors: blood pressure, resting ECG, and age-appropriate cancer screening completed and current BEFORE any growth-factor exposure. §11

Stop and seek medical assessment

§4, §5 — the GH axis

Build muscle / raise GH and IGF-1

Dosing frequency here is arithmetic downstream of half-life, not a protocol choice — and the market sells two pharmacologically different interventions under nearly the same name. Read the pulsatility point before anything else. Every compound in this class is WADA S2: an athlete in a tested sport who follows the source product's base protocol fails a test.

Ranked by evidence strength, strongest first

  1. 1 Programmed resistance training, protein adequacy, and sleep — the upstream GH pulse lives in slow-wave sleep behaviour T1
  2. 2 Somatropin, in its defined indications only — NOT approved for anti-ageing or athletic performance anywhere — narrow drug T1
  3. 3 MK-677 — real human data, and the human data is what shows the downside — not a peptide drug T2
  4. 4 Ipamorelin, GHRP-2, GHRP-6, CJC-1295 peptide T3
  5. 5 Hexarelin, Mod-GRF(1-29) peptide T4
  6. 6 IGF-1 LR3 — research reagent peptide T5
The document corrects this

CJC-1295 WITH DAC has a six-to-eight-day half-life and produces continuous elevation — a 'bleed', not a pulse. 'CJC-1295 without DAC' is a misnomer for Mod-GRF(1-29), which is short-acting and pulsatile. Continuous GPCR stimulation tends toward desensitisation and downregulation. These are different drugs sold under one name. §4

What the class actually does

The feedback point: GHRH analogs and ghrelin-receptor agonists act on the pituitary, so the negative feedback loop through IGF-1 and somatostatin stays intact — there is a ceiling. Exogenous GH and exogenous IGF-1 BYPASS that loop and suppress endogenous production. The claim that peptides 'do not create dependence' is not true across the class. §4

Do not use if

Active or recent malignancy. Active proliferative diabetic retinopathy. Acute critical illness — the 1999 NEJM trial found increased mortality with high-dose GH in ICU patients. Untreated hypothyroidism. Pregnancy and breastfeeding. Benign intracranial hypertension history. Caution in any diabetes or prediabetes: this class worsens insulin sensitivity. §11

Measure first

IGF-1 is essential before anything touching the GH axis, and at every monitoring point thereafter. Fasting glucose and HbA1c on anything metabolic or GH-related. §11

Interactions

GH affects cortisol metabolism via 11β-HSD1 and can unmask previously compensated adrenal insufficiency. It also affects thyroid hormone conversion, which can unmask hypothyroidism. Oral oestrogen reduces the IGF-1 response to GH, so requirements differ. §11

Stop and seek medical assessment

Any new lump, mass, persistent lymph node, unexplained bleeding or unexplained weight loss. Any new, changing, bleeding or asymmetric mole. New persistent headache, visual change or nausea on waking. Spreading redness, heat, swelling or fever at an injection site. New numbness, tingling or hand weakness. Full stop rules in §11.

§5, §15 Pillar 1

Reduce visceral fat specifically

This is the single narrow indication in the document where a GH-axis peptide has full T1 approval — and it is licensed only for HIV-associated lipodystrophy. Its label is the best available guide to what the mechanism does to a human body over a year, including the part performance marketing omits: glucose tolerance worsens in a meaningful fraction of patients.

Ranked by evidence strength, strongest first

  1. 1 Energy balance and fat mass reduction, particularly visceral behaviour T1
  2. 2 Resistance training plus aerobic training behaviour T1
  3. 3 Sleep extension to 7–9 hours behaviour T1
  4. 4 Dietary quality: fibre, protein adequacy, alcohol reduction behaviour T1
  5. 5 GLP-1 / GIP-GLP-1 agonists drug T1
  6. 6 Tesamorelin — in its licensed population — T1 narrow drug T1
What the class actually does

Tesamorelin raises IGF-1 and worsens glucose tolerance — on its own label. §5

Libido and sexual function

There is a genuinely approved T1 option here, with a real label and a hard cardiovascular contraindication — and there is a T6 grey-market compound in the same receptor family that the document includes specifically as the cautionary case for the class.

Ranked by evidence strength, strongest first

  1. 1 Bremelanotide — approved, for hypoactive sexual desire disorder in premenopausal women — narrow indication drug T1
  2. 2 Melanotan II — licenses you to say nothing peptide T6
What the class actually does

Melanocortins: bremelanotide produces a transient blood pressure increase and heart rate decrease, and causes nausea in roughly 40% of patients. Focal hyperpigmentation occurs with repeated use. §8

Do not use if

§8 — neuro / cognitive

Cognition, focus and mood

The two most-cited compounds here are registered medicines — in Russia — with a predominantly Russian-language, single-jurisdiction evidence base. That is T3, not nothing, but it is not what 'clinically proven' implies. The preparation with the widest registration has had unfavourable or inconclusive Cochrane reviews.

Ranked by evidence strength, strongest first

  1. 1 Sleep — restriction measurably degrades cognition and the studies are randomised human designs — §15 Pillar 3 behaviour T1
  2. 2 Semax, Selank — registered in Russia only peptide T3
  3. 3 Cerebrolysin — registered in several countries, Cochrane unfavourable or inconclusive — contested drug T2
  4. 4 Dihexa — preclinical only peptide T4
The document corrects this

Intranasal oxytocin for social and behavioural effects has a large but POORLY REPLICATING literature. The approved obstetric use is T1; the behavioural claim is T3. §8

What the class actually does

Dihexa's potent neurotrophic activity in models means the growth-promotion concern applies to it as it does to BPC-157 and TB-500. §8, §11

§8 — Khavinson bioregulators

Longevity and anti-ageing

The bioregulator concept — that very short peptides act as regulatory signals on gene expression rather than as substrates — is a legitimate hypothesis with real mechanistic proposals behind it. What it does not have is the independent, multi-centre, long-horizon human evidence the marketing implies. A large share of this literature comes from one group in St Petersburg, and independent replication is thin.

Ranked by evidence strength, strongest first

  1. 1 The four T1 behavioural interventions — they are the only things in this document with outcome data at a population scale — §15 behaviour T1
  2. 2 Epitalon, Vilon, Pinealon — single-group, largely in vitro peptide T4
The document corrects this

'Epitalon changed longevity medicine permanently' is not a supportable sentence. Telomerase claims are single-group, largely in vitro, without robust independent replication. §16 erratum 16

What the class actually does

Long-term human data is absent for every compound in this group. Half-lives are not characterised — epitalon's is inferred in minutes — so dosing frequency has no pharmacological basis. §4, §8

§8 — immune

Immune support

There is one genuinely well-evidenced option here, approved in a number of countries. There is also a compound the source material describes as an anti-inflammatory that is, in several contexts, the opposite — and that inversion is a real contraindication signal rather than a nuance.

Ranked by evidence strength, strongest first

  1. 1 Thymosin alpha-1 — approved in a number of countries for hepatitis B and as a vaccine adjuvant drug T2
  2. 2 Thymalin — single-group, Russian-language peptide T3
  3. 3 LL-37 — see the correction peptide T4
The document corrects this

LL-37 is a dual-function molecule. It is antimicrobial, but it is also strongly PRO-inflammatory in several contexts and is mechanistically implicated in the pathology of psoriasis, rosacea and lupus, where it complexes with self-DNA to activate plasmacytoid dendritic cells and drive interferon responses. The source excerpt frames it as an anti-inflammatory, which inverts a genuine contraindication. §8, §16 erratum 9

Gut health and intestinal permeability

The most rigorously tested intervention for intestinal permeability reached Phase 3 and missed its primary endpoint. That is the single most relevant fact for any protocol built on the leaky-gut framing, and it is stronger evidence against than the untested compounds have for.

Purpose. This is the reference layer that the "Prime Peptides" product excerpt does not contain: pharmacology, regulatory status, anti-doping status, evidence tiers, safety architecture, sourcing quality, handling, and protocol design logic. It also corrects the factual errors in that excerpt (§16).

What this document is not. It is not medical advice, and it is not a self-administration manual. Where a compound has an approved label, the label dose is given, because that is public prescribing information. Where a compound has no approval, this document says so and describes what the literature actually used, including the species. It does not construct dosing protocols for unapproved injectables, because there is no evidence base from which to construct one honestly.

§1

How to read a peptide claim — the evidence tiers

T11T21T31T41T51T61

Almost every dispute about peptides is a tier confusion. A mechanism shown in a cell line gets quoted as though it were a clinical outcome. Assign a tier before you assign belief.

TierWhat it meansWhat it licenses you to say
T1Multiple large randomised controlled trials in humans, plus regulatory approval"This causes that, at this dose, with these risks"
T2One or more adequately powered human RCTs, no approval, or approval in one narrow indication only"This has been shown to do that in this population"
T3Small human trials, open-label, uncontrolled, or single-centre"Early human signal, effect size unreliable"
T4Animal studies only"A mechanism exists in rodents"
T5In vitro, ex vivo, or computational only"A molecular interaction exists"
T6Case reports, clinic anecdote, forum consensus, vendor copyNothing

Two structural warnings that apply across this whole field:

§2

What a peptide is, and what keeps getting miscategorised

no tiers cited

A peptide is a chain of amino acids linked by peptide bonds. The conventional cut-off is roughly 2 to 50 residues; longer chains are called proteins. Peptides sit between small molecules and biologics: too large to reliably cross membranes or survive the gut, small enough to be chemically synthesised rather than grown in cells.

Three consequences follow, and they explain most of the practical constraints:

  1. They are digested. Oral peptides are broken into amino acids by gastric and pancreatic proteases. Getting one orally active requires either heavy modification, a permeation enhancer, or both. Oral semaglutide (Rybelsus) uses the absorption enhancer SNAC and still delivers roughly 1% bioavailability.
  2. They are cleared fast. Native peptides have plasma half-lives measured in minutes. Every long-acting peptide drug achieves it through engineering: fatty-acid acylation for albumin binding (semaglutide), a maleimide that covalently binds albumin (CJC-1295 with DAC), D-amino acid substitution, or PEGylation.
  3. They are immunogenic in principle. Anti-drug antibodies are a real phenomenon for peptide therapeutics and are assessed in registration trials. They are not assessed at all for grey-market compounds.

Category errors to stop repeating. The source excerpt and its sales page list several things as peptides that are not peptides:

Listed as a peptideWhat it actually is
NAD+A dinucleotide coenzyme. Not an amino acid chain.
5-Amino-1MQA methylquinolinium small molecule, an NNMT inhibitor.
MK-677 / ibutamorenA non-peptide small-molecule ghrelin receptor agonist.
Endorphins / Substance PGenuinely peptides, but endogenous signalling molecules, not therapeutics you administer.

This matters beyond pedantry. A buyer who believes NAD+ is a peptide will apply peptide handling, peptide sourcing logic, and peptide risk assumptions to a molecule that shares none of them.

§3

Corrected history

no tiers cited

The excerpt's chronology contains several errors. Here is the corrected version.

The hypothalamic releasing factors. Roger Guillemin and Andrew Schally independently isolated and characterised the hypothalamic releasing hormones across roughly 1969 to 1973, working from enormous quantities of animal hypothalami. Thyrotropin-releasing hormone (TRH, 3 residues) was characterised in 1969. Gonadotropin-releasing hormone (GnRH, 10 residues) followed in 1971. Somatostatin (14 residues) was isolated by Guillemin's group in 1973.

They shared the 1977 Nobel Prize in Physiology or Medicine with Rosalyn Yalow, who was recognised separately for developing radioimmunoassay. The excerpt gives 1975 for the isolation and appears to conflate the two dates.

The "four neuropeptides of up to 14 amino acids" claim is not sustainable. Three of the classical hypothalamic peptides fit that description. The other two canonical members do not: corticotropin-releasing hormone (CRH), characterised by Wylie Vale's group in 1981, is 41 residues; growth hormone-releasing hormone (GHRH), characterised in 1982, is 44 residues.

Endogenous opioids. John Hughes and Hans Kosterlitz identified the enkephalins in 1975 and published in Nature. The excerpt has this right.

Candace Pert. Pert identified the opiate receptor with Solomon Snyder in 1973, as a graduate student, using radioligand binding. Her work extending neuropeptide receptor mapping into immune cells came later, through the 1980s. The 1985 paper often cited here is "Neuropeptides and their receptors: a psychosomatic network" in the Journal of Immunology. "Molecules of Emotion" is the title of her 1997 popular book, not a term coined in 1985.

BPC-157 does not belong in a 1980-1990 section. It is a synthetic 15-residue sequence derived from a fragment of a protein found in human gastric juice, developed by Predrag Sikirić and colleagues at the University of Zagreb. The published work begins in the early-to-mid 1990s, not the 1980s.

Mitochondrial-derived peptides. Humanin, a 24-residue peptide encoded in the mitochondrial 16S rRNA region, was reported in 2001 in the context of protection against amyloid-beta toxicity. MOTS-c, a 16-residue peptide encoded in the 12S rRNA region, was reported in 2015 in Cell Metabolism by Lee, Cohen and colleagues. The excerpt's 2015 date for MOTS-c is correct.

§4

Pharmacokinetics — why half-life dictates everything

no tiers cited5 unverified

Dosing frequency is not a preference, a tradition, or a protocol design choice. It is arithmetic downstream of half-life. A compound with a 30-minute half-life administered once daily is present at meaningful concentration for well under an hour out of 24. Any protocol that ignores this is describing a ritual, not a pharmacological exposure.

The pulsatility point. Endogenous growth hormone is released in pulses, concentrated in early slow-wave sleep. The GH axis is regulated by that pulse pattern, and somatostatin tone between pulses is part of the signal. A short-acting GHRH analog produces a pulse. CJC-1295 with DAC does not — its six-to-eight-day albumin-bound half-life produces a continuous elevation, often called a "bleed." These are pharmacologically different interventions that the market sells under nearly the same name. Continuous stimulation of a G-protein-coupled receptor tends toward desensitisation and downregulation.

The feedback point. GHRH analogs and ghrelin-receptor agonists act on the pituitary, so the negative feedback loop through IGF-1 and somatostatin stays intact — there is a ceiling. Exogenous GH and exogenous IGF-1 bypass that loop and suppress endogenous production. The excerpt's claim that peptides "do not create dependence" is not true across the class; it is true for some mechanisms and false for others.

It is the proof that a GHRH analog can clear a full regulatory pathway, and its label is the best available guide to what this mechanism actually does to a human body over a year: visceral fat falls, IGF-1 rises, glucose tolerance worsens in a meaningful fraction of patients. That last item is routinely omitted from performance marketing.

Presenting it as an available performance tool overstates a program with a mixed trial record.

The honest summary of this section: the regenerative peptides that dominate the marketing have the weakest evidence in the document, and the two compounds in this class that were tested most rigorously in humans — larazotide and elamipretide's myopathy trial — both missed their endpoints.

The bioregulator concept — that very short peptides act as regulatory signals on gene expression rather than as substrates — is a legitimate hypothesis with real mechanistic proposals behind it. What it does not have is the independent, multi-centre, long-horizon human evidence that the excerpt's framing implies. "This changed longevity medicine permanently" is not a supportable sentence.

§9

Regulatory status map

no tiers cited

The excerpt's central regulatory claim is that peptides cannot be patented and therefore cannot be developed. This is false, and it is load-bearing for the whole argument, so it is worth dismantling precisely.

The patent claim is wrong

The claimThe reality
"Peptides are identical to molecules the body produces, so cannot be patented"Naturally-occurring sequences as such are generally not patentable, but analogs, modifications, formulations, delivery systems, manufacturing processes, and specific medical uses all are.
"No patent = no exclusivity = nobody invests"Semaglutide, tirzepatide, tesamorelin, teduglutide, setmelanotide, bremelanotide, liraglutide and afamelanotide are all patented peptide drugs. The GLP-1 class alone represents one of the largest revenue events in pharmaceutical history.
Implied conclusion: absence of approval reflects economics, not evidenceSometimes true, sometimes not. Sermorelin's withdrawal was commercial. AOD-9604's absence is a failed trial. Larazotide's absence is a failed Phase 3. Elamipretide's mitochondrial myopathy indication is a missed primary endpoint. Presenting all absence as economic is the key rhetorical move of the source material and it does not survive contact with the trial record.

The honest version of the argument is narrower and still worth making: for unmodified endogenous sequences with no viable exclusivity position, commercial sponsorship is genuinely absent, and so the evidence base stays thin indefinitely. That is true of BPC-157. It is not true of the field.

On trial costs: the excerpt's per-phase figures ($50M / $120M / $500M) are presented as fixed facts. The published estimates in this area, principally from the Tufts/DiMasi line of work and its critics, are capitalised cost per approved drug including failures and cost of capital, not out-of-pocket cost per phase, and the estimates vary by an order of magnitude between authors. Quote a range with a source or drop the numbers.

United StatesFDA approval; plus compounding under FD&C Act sections 503A (pharmacies) and 503B (outsourcing facilities). In 2023 FDA placed a batch of peptides — including BPC-157, ipamorelin, epitalon, KPV and thymosin beta-4 fragments — in category 2, meaning significant safety risks identifiedCategory 2 listing effectively ended lawful compounding of those substances. This is an affirmative regulatory finding, not merely an absence of approval — which is the opposite of the excerpt's "regulatory gap is not danger" framing for these specific compounds.

Prescription medicines require a prescription. There are separate provisions governing personal importation of prescription medicinesThese are the mechanical provisions. Whether any particular activity falls inside or outside them is a question for a lawyer or for Medsafe directly, and this document does not answer it.

The "research use only" mechanism

Grey-market peptide supply operates by labelling product "for research use only, not for human consumption." That label is the entire legal architecture of the sector. It also means, mechanically, that the product is not manufactured, tested, released, or stored to pharmaceutical standard, and that no pharmacovigilance system exists behind it.

§10

Anti-doping status

no tiers cited1 unverified

This is the single largest omission in the source material. The product is sold to "the modern athlete" and contains no mention of anti-doping status at all. An athlete in a tested sport who follows its base protocol fails a test.

The World Anti-Doping Agency Prohibited List is revised annually and takes effect on 1 January. Categories relevant here:

CategoryCoversCompounds in this document
S0 — Non-approved substancesAny pharmacological substance with no current approval by any governmental regulatory health authority for human therapeutic useCatches BPC-157, MOTS-c, epitalon, and most of the research-only list by default

S4 — Hormone and metabolic modulatorsIncludes metabolic modulators; AMPK activators such as AICAR are explicitly listedMOTS-c falls in this logic as an AMPK activator
S5 — Diuretics and masking agentsNot relevant here

BPC-157 was added to the prohibited list in 2022. GLP-1 receptor agonists such as semaglutide and tirzepatide are not, as of this document's knowledge, on the prohibited list — but weight-class sports and individual federations may have their own rules, and the list changes yearly.

Verify every line of this table against the current Prohibited List at wada-ama.org before publishing. An out-of-date anti-doping table in a commercial product is a serious liability.

Additional bodies with their own lists: national anti-doping organisations, UFC/USADA-style promotion-specific programmes, the NCAA, professional league programmes, and the military drug policies of several countries. A "not on the WADA list" finding does not clear a substance under all of them.

Growth-factor and angiogenic repair peptides (BPC-157, TB-500, dihexa)Any history of malignancy, and any undiagnosed lump, lesion or bleeding, until investigated. The concern is mechanistic and unquantified; that is a reason for caution, not reassurance.
Immune modulators (thymic peptides, LL-37)Autoimmune disease. Solid organ transplant or any immunosuppression. LL-37 specifically: psoriasis, rosacea, lupus.
All classesPregnancy, breastfeeding, and under-18s: no safety data exists for any of the unapproved compounds in any of these populations.

Baseline panel

Nothing in this field is interpretable without a before. The excerpt tells the reader to "evaluate CRP and IL-6 at week 9" without ever establishing a baseline, which makes the week-9 number uninterpretable.

Metabolic: fasting glucose, fasting insulin (compute HOMA-IR), HbA1c, full lipid panel including ApoB, liver enzymes, renal function and eGFR.

Endocrine: IGF-1 (essential before anything touching the GH axis), TSH and free T4, total and free testosterone, SHBG, LH, FSH, oestradiol, prolactin, morning cortisol.

Inflammatory: hs-CRP. Note that IL-6 is not a standard clinical monitoring assay — it is short-lived, highly variable, rises acutely with exercise, and is not validated for tracking "chronic silent inflammation" in an individual. Building a protocol around serial IL-6 is measurement theatre.

Haematology and other: full blood count, ferritin, vitamin D, B12, folate, homocysteine.

Additional before incretins: lipase and amylase; calcitonin only if history warrants; thyroid and family history documented.

Additional for anyone over 40 or with risk factors: blood pressure, resting ECG, and age-appropriate cancer screening completed and current before any growth-factor exposure.

Monitoring cadence

Baseline, then week 6 to 8, then week 12, then quarterly. IGF-1 specifically on anything touching the GH axis, at every point. Fasting glucose and HbA1c on anything metabolic or GH-related.

Sourcing, purity and the certificate of analysis

The sales page defers this entirely to a bonus. It is not a bonus. It is the difference between the molecule you think you have and the one in the vial.

What a certificate of analysis must contain

ItemWhat it provesWhat "missing" means
Identity by mass spectrometry (ESI-MS or MALDI-TOF) with observed vs theoretical molecular weightThe vial contains the sequence claimedWithout it you have no evidence the compound is what the label says
Purity by HPLC, with the chromatogram, not just a numberHow much of the material is the target peptideA stated "99%" with no trace is an assertion
Impurity profileWhat the other 1 to 5% is: truncated sequences, deletion or insertion sequences, D-isomer epimers, oxidation productsImpurities in a synthetic peptide are structurally related to the target and are the main immunogenicity and off-target risk
Counterion / salt form and net peptide contentWhether "5 mg" is gross or netThis is the most common silent dosing error in the sector. Synthetic peptides are usually isolated as TFA or acetate salts. A vial labelled 5 mg may contain 5 mg of salt, of which perhaps 75 to 85% is peptide. That is a 15 to 25% overstatement of what you are actually administering.
Water content (Karl Fischer)Residual moisture affecting mass and stability
Endotoxin (LAL assay, EU/mg), lot-specificBacterial pyrogen contaminationAn injected endotoxin load causes fever, chills, and systemic inflammatory response. Research-grade material is frequently not tested for this.
SterilityResearch-grade material is generally not sterile-filled
Residual solventsSynthesis reagent carryover
Lot number and date matching the vial in your handThat this CoA describes this batchA generic PDF from a website describes nothing

The trust chain

A vendor-supplied CoA is a vendor's claim. Independent third-party testing on the specific lot, commissioned by someone with no financial interest in the result, is evidence. Published analyses of grey-market peptide products have repeatedly found under-dosed vials, mislabelled compounds, and products containing something other than the labelled substance. Locate and cite specific published analyses before publishing this section — do not rely on the general claim.

Why the compounding route mattered

Before the FDA category 2 listing, a 503A compounding pharmacy in the US provided a route where the product was made under pharmacy standards, on a prescription, with a practitioner in the loop. The category 2 listing closed that route for the named substances, which pushed demand toward research-chemical supply, which has none of those controls. That is a real and under-discussed consequence of the regulatory action.

§13

Handling — reconstitution arithmetic, storage, sterility

no tiers cited

Included because dosing errors of a factor of ten are the most common serious harm in self-administration, and the arithmetic that prevents them is generic pharmacy maths.

The concentration calculation

Concentration equals total peptide mass divided by diluent volume.

A U-100 insulin syringe is graduated in units where 100 units = 1 mL, so 1 unit = 0.01 mL. This is the conversion where errors happen.

Worked example, purely as arithmetic:

Vial contains        : 5 mg peptide (net, after checking salt form)
Diluent added        : 2 mL bacteriostatic water
Concentration        : 5 mg / 2 mL = 2.5 mg/mL = 2500 mcg/mL
1 insulin unit       : 0.01 mL
Peptide per unit     : 2500 mcg/mL x 0.01 mL = 25 mcg per unit

Change the diluent volume and every subsequent number changes. Write the concentration on the vial in permanent marker at the moment of reconstitution.

Diluent choice

Technique

Storage

Route

Subcutaneous, intramuscular, intranasal and oral are not interchangeable. Route determines bioavailability, onset, and in some cases whether the compound reaches the target at all. Site rotation prevents lipohypertrophy and local reactions.

What this section does not cover

Combining two compounds in one vial or one syringe. Nothing in this document addresses physical co-mixing: whether two peptides are chemically compatible in solution, what a shared diluent does to the stability of either, whether one compound's counterion or pH affects the other, or how co-mixing changes adsorption to the vial and syringe surfaces. This is a real and commonly asked question and the honest answer here is that this reference cannot answer it.

Note that the practice is widespread and the silence is not endorsement. Compatibility is a formulation question with a compound-by-compound answer, and for the research-only compounds it is unlikely that anyone has generated the data at all — the stability figures for a single compound in bacteriostatic water are already largely unpublished, as noted above. See the verification queue, item 16.

Separately, and distinct from this: whether you should be running several compounds at once is a protocol-design question, not a handling one, and §14 principle 3 answers it.

§14

Protocol design principles

no tiers cited

Not prescriptions. The logic that separates a protocol from a ritual.

  1. Frequency follows half-life. See §4. Any schedule that is not derived from the compound's own kinetics is arbitrary.
  2. Pulsatile and continuous are different drugs. Especially on the GH axis. Continuous GPCR stimulation drives desensitisation.
  3. Change one variable at a time. Stacking four compounds and reporting that "the protocol worked" produces no information. This is the single most common failure in the entire field, and it is what allows ineffective compounds to accumulate reputations.
  4. Define the endpoint before you start, and make it measurable. "Better recovery" is not an endpoint. Grip strength, a specific lift at a specific RPE, hs-CRP, HOMA-IR, DEXA body composition, sleep-stage data, or a validated pain score are endpoints.
  5. Baseline for long enough to see your own variance. Most biomarkers move substantially week to week for reasons unrelated to any intervention.
  6. People start protocols at their worst. Regression to the mean will produce improvement in the absence of any effect. So will placebo, which is large for subjective endpoints like pain, energy and mood — precisely the endpoints this field markets on.
  7. Minimum effective exposure, and a defined stop. Open-ended use of a compound with no long-term human safety data is an uncontrolled experiment with a sample size of one and no follow-up.
  8. Washout and re-baseline before assessing anything new.
  9. Time-to-signal differs by mechanism. Metabolic effects appear in weeks. Body composition takes months. Tissue repair is on the timescale of tissue repair, which no signalling molecule shortens below the biological floor.
  10. Confirm the boring variables are fixed first. If sleep is 5 hours, protein intake is inadequate, alcohol is regular, or training is unprogrammed, no peptide is the limiting factor, and any effect will be swamped.

§15

The three pillars, corrected

T17T423 unverified

The excerpt's triad — insulin resistance, chronic inflammation, sleep dysregulation — is a reasonable organising frame. The mechanisms as written contain errors, and the intervention hierarchy is inverted.

Pillar 1 — insulin resistance

What the excerpt gets wrong. It states that a stress signal via CRH and cortisol "lowers blood glucose." Cortisol raises blood glucose, through hepatic gluconeogenesis and peripheral insulin antagonism. That is the entire point of the stress response. It also says "almost all glucose goes to fat tissue instead of muscle," which misstates the physiology: skeletal muscle is the site of roughly 70 to 80% of insulin-stimulated glucose disposal, and in insulin resistance muscle uptake falls while hepatic de novo lipogenesis rises.

What is actually established. Impaired GLUT4 translocation to the membrane, rather than simple receptor "downregulation," is the proximate defect in muscle. Critically, muscle contraction stimulates GLUT4 translocation through an insulin-independent, AMPK-linked pathway. This is why exercise improves glucose disposal in people whose insulin signalling is impaired, and it is the most robustly evidenced intervention available.

Measurement: fasting glucose with fasting insulin, computed as HOMA-IR; HbA1c; triglyceride-to-HDL ratio; ApoB; an oral glucose tolerance test with insulin if the picture is unclear.

Intervention hierarchy by evidence strength:

RankInterventionTier
1Energy balance and fat mass reduction, particularly visceralT1
2Resistance training plus aerobic trainingT1
3Sleep extension to 7–9 hoursT1
4Dietary quality: fibre, protein adequacy, alcohol reductionT1
5MetforminT1
6GLP-1 / GIP-GLP-1 agonistsT1
7Tesamorelin, for visceral fat, in its licensed populationT1 narrow
8MOTS-c, 5-Amino-1MQT4 — rodent

The excerpt's "molecular solutions" section presents rank 8 as the answer and does not mention ranks 1 through 4.

Pillar 2 — inflammation

What the excerpt gets wrong. It treats IL-6 as uniformly pathological. Skeletal muscle releases IL-6 during exercise as a myokine, and that exercise-induced IL-6 signal has net anti-inflammatory downstream effects, including induction of IL-10 and IL-1ra. Conflating exercise-derived IL-6 with adipose- and macrophage-derived chronic IL-6 is a substantive error, and it leads directly to the wrong conclusion, which is to suppress a signal that is part of the adaptation.

It also inverts LL-37, as noted in §8.

What is usable. hs-CRP is the practical marker, it is standardised, and it has outcome data behind it. "Chronic silent inflammation" is not a diagnosis and has no diagnostic criteria; it is a useful shorthand and should be labelled as one.

Established drivers of low-grade systemic inflammation: adiposity, particularly visceral; insufficient sleep; alcohol; smoking; periodontal disease; low dietary quality; physical inactivity; untreated sleep apnoea.

Intervention hierarchy: the same first four ranks as Pillar 1, plus treatment of periodontal disease and sleep apnoea where present. The peptide options in the excerpt's anti-inflammatory protocol — BPC-157, KPV, LL-37, SS-31 — are T4 for this purpose, and the one intervention in this space that received a properly powered human trial, larazotide for intestinal permeability, missed its endpoint.

The excerpt's "anti-inflammatory base protocol" — BPC-157 alone weeks 1-2, add SS-31 weeks 3-4, add MOTS-c weeks 5-8 — has no dose, no route, no frequency, and combines three compounds with no human efficacy data in a sequence that makes attribution impossible. It also violates its own principle of measurement by placing the first biomarker check at week 9, with no baseline.

Pillar 3 — sleep and the nocturnal axis

This is the pillar the excerpt truncates, and it is the one with the strongest human evidence. That inversion is the clearest single indicator of the document's priorities.

What is established in humans, with controlled designs:

The implication. These are randomised or crossover human studies with effect sizes larger than anything demonstrated for any unapproved peptide in this document, and the intervention is free. A product that positions itself as a performance system and truncates this section while leading with BPC-157 has its hierarchy exactly backwards.

Peptide angles, honestly stated: DSIP has essentially no human evidence of sleep induction. GHRH administration has been shown to modestly increase slow-wave sleep in research settings, which is mechanistically interesting and not a licensed use. Nothing here competes with sleep opportunity, timing regularity, light exposure, alcohol removal, and treatment of undiagnosed sleep apnoea.
