▸ Vendor trust leaderboard
Peptide vendor trust leaderboard
Every research-peptide vendor we track, ranked by a composite 0–100 Trust Score built from third-party lab COAs — purity %, dose accuracy, batch consistency, endotoxin pass rate, and public verification. The same score that powers our internal vendor board, now public. No vendor influence, no pay-to-rank.
Most trusted
Highest composite Trust Scores in the corpus — the vendors with the strongest, most recent lab evidence.
Lowest composite scores
The vendors with the lowest composite Trust Scores and most flagged batches in our corpus. This is a score derived from lab data, not an accusation — open a vendor to see the evidence and any documented incident.
Full ranking
All 1084 tracked vendor profiles, ranked best → worst by composite Trust Score. Vendors without enough lab data to score yet trail at the bottom.
Aggregate scores + headline COA counts only. Per-batch purity distributions and per-compound breakdowns are on each vendor's profile (TitrateLab Pro). See the methodology for weights, recency-weighting, and known caveats.
