Score breakdown

How this is scored →

Low score?Most scraped COAs land here. Vendors who claim their profile and upload COAs directly — and whose labs run the full panel (endotoxin, microbial/sterility, heavy metals, net peptide content) — score higher. The math is honest about what's actually been tested.

Avg Purity(30% weight)

Mean HPLC purity across published COAs

Safety Panel Coverage(40% weight)

Per-peptide coverage of identity / endotoxin / microbial / heavy-metals / net-content panels

Lab Corroboration(15% weight)

Lab corroboration tier — confirmed via public verify portal (90), presumptive trusted lab (85), lab resolved but unverified (75), or no lab attribution (50)

Forgery Signals(15% weight)

We are continuously testing more products. Scores update with each new result.

Read our scoring methodology →

Trust scores are computed from indexed Certificates of Analysis — vendor-published, and lab-confirmed where a lab copy verifies them — using a fixed, versioned methodology (v13). They are not based on independent blind-purchase testing, and no vendor can pay for placement or a higher score. How we score · How we make money
