We index every public Certificate of Analysis from every vendor we can find, parse them with structured extraction, and score the results — including failures. No vendor can pay to influence their score; no paid placements.
We score what vendors themselves publish — their own Certificates of Analysis from the labs they chose. Vendors cannot pay to influence their score, hide failures, or remove their listing. We publish everything we can verify.
Four weighted components, computed from every Certificate of Analysis we index across the corpus. Recomputed nightly + on every consent flip, lab confirmation, or new upload. Full methodology →
HPLC purity across each vendor's published COAs, normalized through a piecewise curve (99% → 95, 95% → 60, 90% → 30).
Fraction of five panels reported per peptide: identity (mass-spec/LC-MS or FTIR), endotoxin (USP <85>), microbial safety (USP <61>/<71>), heavy metals (ICP-MS), and net peptide content (mg per vial).
69 vendors scored from published Certificates of Analysis. Composite weights purity, safety-panel coverage, lab corroboration, and forgery risk. 27 vendors show as ND (Not enough data) — fewer than 10 COAs, so listed but not yet given a letter grade. This applies to claimed and unclaimed vendors alike, so a grade can't be gamed with a thin sample.

Mirror upload from both lab and vendor → 100. Lab confirms authorship → 90. Named indexed lab → 75. Unresolvable lab → 50. Lab-disputed → 0.
Inverse of CoaFlag count — lot collisions across vendors, perceptual-hash collisions, suspiciously narrow lab variance, claim-not-tested mismatches.
Independent multiplier (0.30×–1.10×) applied on top of the composite. Composed from WHOIS domain age, Twilio phone-line classification, Google Places address verification (catches Private Mailboxes and shared-office buildings), and lab-corroboration coverage. Clean identity earns a small bonus; entirely self-attested document corpora hit the floor. Full disclosure on /methodology.
