What is and isn't established about a commercial peptide catalogue

Updated 2026-08-09 · Protocol v1.0 · 51 SKUs · 4 of 43 records complete

An evidence map of a class of widely-used compounds, graded on three independent axes, with every claim carrying a source and a retrieval status — and every gap stated rather than smoothed over.

What this isA description of the evidence: what was studied, in what species, by what route, at what dose, and what happened. Absences are recorded as findings with dates.
What this is notNot a purchasing guide. No dosing protocols, no administration guidance, no sourcing advice, no recommendations. Doses appear only as facts, for the route/dose mismatch check.

01Scope corrections

The working assumptions going in were wrong in four ways. Recorded because scope discovered mid-project invalidates batching.

AssumptionWhat the catalogue actually shows
~40 catalogue items51 SKUs, resolving to 43 distinct compounds and blends. Under-counted by roughly a third.
A full Khavinson bioregulator line — Chonluten, Pinealon, Cortagen, Prostamax, Vilon, ThymalinNone of these are stocked. The Khavinson-type line is exactly three: Epitalon, Cartalax, Bronchogen.
Adamax and Bronchogen were missed by the prior passCorrect. Both present, both added July 2026 per image upload paths.
13 compounds went unanticipated entirely: LL-37, VIP, ARA-290, Snap-8, AHK-cu, AOD-9604, Thymosin α1, Survodutide, Sermorelin, Cagrilintide, DSIP, Melanotan I, Lipo-C.
Consequence

Semax itself is not sold — only N-acetyl semax amidate and Adamax, both analogues that inherit nothing. So FDA's Semax review, one of the seven, attaches to no catalogue item directly. That is the reverse of the assumption going in.

02Key findings so far

From one completed record and the catalogue enumeration. Ironic findings held to a higher evidentiary bar, not a lower one.

DSIP is emideltide — the one compound the committee rejectedverified

The catalogue sells DSIP 10mg at $178/kit. FDA's meeting page states that the substance it reviewed as Emideltide is "also referred to as delta sleeping inducing peptide (DSIP)."

So the only one of the seven the PCAC declined to recommend is stocked here under its non-INN name. A direct identity link from a primary source, not an inference.

FDA found no clinical studies of BPC-157 in tendonitisload-bearing

BPC-157 was nominated for ulcerative colitis, Crohn's, celiac and tendonitis. FDA evaluated only UC, stating in footnote 4:

"FDA did not evaluate the proposed uses of Crohn's disease, Celiac disease, and tendonitis because the nomination did not include sufficient information … In addition, FDA did not identify clinical studies using BPC-157 in these populations."

A dated, primary-source statement of absence covering the musculoskeletal indication that drives essentially all demand.

source: FDA Briefing Document, BPC-157-related BDSs, 11 May 2026, fn. 4 · retrieval: retrieved
Popularity runs inverse to clinical footprintpartly corroborated

FDA's outsourcing-facility database recorded zero compounded BPC-157 products between January 2017 and June 2025. Over the same period, per a paper FDA quotes, June 2024 search volume hit an all-time high with more than 50 million tagged video views on each of YouTube and TikTok.

Exactly the kind of finding a writer is drawn to, so: the database figure is a direct regulatory record; the social figure is attributed to Vasireddi et al. 2025 which has not been opened. The regulatory half stands; the social half is provisional.

Every nomination was withdrawn before the meetingverified

All nominations — LDT Health Solutions on behalf of the International Peptide Society, and Wells Pharmacy Network — were withdrawn by the nominator before the July meeting. FDA proceeded with all seven evaluations anyway, on its own initiative.

Bears on Source Independence, and withdrawing a nomination is an unusual posture for a substance its proponents are said to believe in.

On the "sold for" column

These are market facts, not endorsements — what the compound is marketed and discussed for, recorded so the Indication Match axis has something to compare against. For BPC-157 the claims are quoted from clinic and pharmacy pages collected by FDA. For the rest they are currently characterisations of the market positioning and get verified against vendor pages during each compound's Phase 2 pass (step 6 of the search order, market facts only). Until then treat the column as provisional.

Two unresolved identity questions

TB4 vs TB-500. The vendor sells both as separate SKUs, implying TB4 is full-length thymosin β4. FDA reviewed "TB-500." If those differ, the FDA review does not cleanly attach to this SKU.

Bronchogen sequence. AEDL (Ala-Glu-Asp-Leu) vs Ala-Asp-Glu-Leu (= ADEL). Different molecules, not two spellings of one. Flagged, not resolved by preference.

06Vote record — a provenance problem

The most important epistemic caveat in the project so far.

Excluded from synthesis by decision of 8 Aug 2026

FDA had not posted minutes or a transcript as of 6 Aug 2026, and the primary record is two YouTube webcasts that cannot be watched with available tools. Every tally below is ⚠ learned-from-summary and may not appear in any synthesis, table or summary until upgraded.

The figures came from the project brief rather than from a vendor. That does not change their status — same failure mode, no exception for trusted sources.

08Method & rubric

Enforced search order

Not reorderable. A previous pass wrote this order then searched conversationally instead, which returned vendor SEO content and contaminated the dataset.

  1. ClinicalTrials.gov
  2. FDA PCAC 2026 docket extracts
  3. PubMed, Species: Human filter ON, then RCT / systematic review / meta-analysis filters
  4. PubMed, no species filter — only if 3 returns nothing
  5. PMC / DOI full-text resolution
  6. Vendor pages — last, market facts only, never for an evidence claim

Stopping rule. If 1–4 return no human study of any design, cap at L5, record the dated absence, move on.

Evidence Level

L1Systematic review of RCTs, or multiple large consistent RCTs
L2≥1 adequately powered RCT with a prespecified primary endpoint
L3Non-randomised controlled or cohort study
L4Case series, case-control, uncontrolled observational, or conference abstract
L5In vitro, animal, or mechanistic reasoning only

(provisional) is appended where a grade rests on sponsor announcements rather than peer-reviewed publication.

Provenance — two fields on every claim

source: <PMID / NCT / DOI / named document>
retrieval: retrieved | abstract-only | ⚠ learned-from-summary

⚠ learned-from-summary means the figure was encountered in someone else's description of a study that was not then opened. It may stay in the dataset; it may not be used in any synthesis until upgraded. This applies to figures supplied in the project brief itself.

Working rules

  • Absence is a finding. "No registered trials as of <date>" is a result.
  • Never smooth over a discrepancy. Flag and move on rather than resolving by preference.
  • Watch for narrative pull. Ironic findings get a higher evidentiary bar.
  • No recommendations. If a sentence would work as marketing copy, rewrite it.

09Limitations

What could not be reached, so the next pass knows where the soft spots are.

IssueEffectStatus
Literature retrieval — SOLVEDDirect PubMed page fetches hit a reCAPTCHA on the second consecutive request. NCBI E-utilities (esearch.fcgi / efetch.fcgi) returns clean abstracts with no rate-limiting and should be the default from now on. Five primary sources retrieved this way on 9 Aug 2026, clearing every outstanding efficacy figure in the Tesamorelin and Ipamorelin recordsresolved
ClinicalTrials.gov unreachableReturns an empty response body on both the v2 API and the legacy full_studies endpoint; study pages are client-rendered. Step 1 of the search order still cannot be executed directly. Workaround: where a trial is published, the paper carries its own NCT identifier and is a better source than the registry entry — that path resolved NCT00672074 and NCT00123253. It does not substitute for a current search of unpublished or ongoing trials, which remains undoneOpen — partially mitigated
Corrections made 9 Aug 2026Three claims were wrong or over-stated and have been fixed in place, each with an inline note: (1) a safety statement attributed to Gobburu 1999 that the paper does not contain — struck; (2) tesamorelin glucose intolerance presented as an established liability when both pivotal trials found no significant glycaemic difference — now presents label warning and trial result together; (3) tesamorelin VAT "reverts toward baseline on withdrawal" — not supported by the retrieved abstract, withdrawn and reframed as an open questionremediated
Ipamorelin Phase 2 characterisationOriginally described as having "failed." The published result is a 7.3-hour median advantage at p=0.15 in 114 patients — underpowered rather than flatly negative. Reframed throughoutremediated
PCAC vote record is video-onlyPrimary record is two YouTube webcasts; no minutes as of 6 Aug 2026Open — tallies excluded
Large FDA PDFs exceed response limitsEach must be fetched to disk and read in chunks — slow for the remaining sixManaged

Structural gaps in the evidence base itself

Findings about the field, not failures of this project.

  • No observational tier. For most of this catalogue there is nothing between rodent studies and marketing copy — no registries, no cohorts, no post-marketing surveillance, because there is no marketing authorisation to surveil.
  • FAERS undercounts structurally. 503A compounders generally do not report to FDA; research-chemical vendors are outside the system entirely. Counts are floors of unknown tightness, never rates.
  • Certificates of analysis report purity only. Impurity profiles, aggregation state and endotoxin are typically untested — "99% pure" constrains far less than it appears to.

Each completed compound ships as a standalone HTML file in compounds/ — self-contained, no shared dependencies, so it can be saved or shared on its own. Markdown working copies, FDA source extracts and the protocol are in working/.

Records are kept as separate files because Phase 4 requires auditing in a session holding only the records — same-session auditing shares the writer's blind spots.
