Independent peptide vendor verification.
Merit Verified catalogs independent COA evidence for peptide vendors. Phase 1 ships the evidence layer: 2,500+ third-party COAs linked to peptide, lab, lot, batch, and test date. The trust signal is the evidence itself — lab name, measured purity, test date. Merit Verified's own evaluative score arrives in Phase 2 with a documented methodology. Built so you can stop reading a dozen subreddits before every order.
Our principles
No paid placement
Trust signals cannot be bought. No vendor pays to appear higher in the directory or to remove a flag.
Methodology in the open
Phase 1's signal is the COA evidence itself: third-party lab, measured purity, test date, batch. We do not compute an evaluative score this phase. When Merit Verified's own 0–100 score ships in Phase 2, the rubric, weights, and data sources will be documented here. Score moves will get a changelog entry.
Evidence updates as tests land
The catalog updates on a rolling basis as new third-party COAs are indexed. The reading you see is current as of the most recent re-index — not a permanent verdict.
No commercial entanglement
The Merit Verified team does not manufacture peptides, hold equity in vendors we surface, accept compensation tied to specific listings, or process orders.
What we surface this phase
Phase 1 surfaces the COA evidence itself. Merit Verified does not assign a vendor grade or score this phase. The signal is what's been tested, where, by whom, and when.
- COA evidence — third-party tests
- 2,500+ third-party tests on file, each linked to peptide, lab, lot, batch, and test date. Sorted recency-first; NULL-purity rows sort last. Linkable, auditable, third-party-issued. This is the only trust signal this phase.
- Catalog scale
- 2,500+ COAs on file, 1,100+ lots tracked, 20+ independent labs, 40+ peptide vendors. Numbers update as new evidence is indexed.
What's coming in Phase 2
Merit Verified's own 0–100 trust score, built on the COA evidence base. The methodology is in development and will be published in full when the score ships. Until then, the trust signal is the COA evidence itself — what tests have been run, by which independent labs, on which lots.
Changelog
2026-05 · Migration to scrape-first COA catalog. COA dataset grew from 2,167 (pre-migration) to 2,523 (current) — 1.16× — through
direct ingestion of an independent third-party scrape. Retention rate against the
2,971-row raw snapshot was ~84.9%; the 448 COAs and 362 lots that didn't resolve to
a canonical peptide slug are preserved in the project repo at data/_unresolved/coas-skipped.json and data/_unresolved/lots-skipped.json with re-import provenance intact for Phase 2.
Phase 2 deliverables, deferrals, and design questions are tracked in data/_unresolved/PHASE-2-PLAN.md.
The central deliverable is Merit Verified's own evaluative score methodology
(currently parked — Phase 1 surfaces the COA evidence as the only trust signal).
A short note on what this is not
This is not medical advice. The research-only regulatory status on most peptide listings is not a marketing flourish — it's the actual legal framing. Talk to a clinician who knows your full picture before doing anything with this information.
This is not a sales channel. Merit Verified does not stock, ship, or process orders. Listing URLs go directly to vendor sites. The trust score determines the order vendors appear in; it does not endorse purchase.
This is not the whole picture. Peptide vendors operate in a grey market with limited public disclosure. We score what's observable. Where evidence runs thin, we say so.
