What this is
A community-maintained directory of research peptides, their upstream manufacturers, the storefronts that resell them, and the independent test results (COAs) that confirm or contradict vendor claims.
Every record is sourced. Every score is derived from inputs you can inspect on the entity's page. Nothing here is medical advice or an endorsement to purchase or use any compound — most peptides listed are not approved for human therapeutic use.
Trust score methodology
Every vendor starts at 50 points. Adjustments: + up to 25pts from certifications held by the vendor's linked manufacturer (GMP, ISO, etc.) + up to 25pts from recent independent COAs (decays linearly over 1 year) + up to 10pts for years active (0.5pt/year) + up to 15pts from third-party rankings (#1 = 10pts, #2-3 = 6pts, #4-10 = 3pts) + up to 10pts from review sentiment (needs ≥3 reviews; +0 at avg 3★, +8 at 5★) − 10pts if no independent COA is on file − 30pts if marked "closed" Vendors marked "scam-flagged" are floored to 0. Scores are recomputed every time data is re-seeded. Per-vendor breakdowns are stored alongside the score so any number can be traced to its inputs.
Data sources
Scraped from public vendor websites, manufacturer disclosures, third-party
rankings (such as reptides.co/market),
and academic citation databases. Every record carries a _meta
block with its source URL and verification timestamp.
