The peptide vendors you can actually trust
We don’t sell peptides — we grade the vendors who do, on third-party lab tests, measured purity, and real buyer evidence.

How the grade works
Every vendor is scored 0–100 across weighted trust factors. A vendor with no independent COA can’t score above a D; fabricated COAs are capped at F.
Lab testing & COA
43%
Independent third-party COAs (e.g. Janoshik), HPLC purity, accredited labs — verified, not vendor say-so.
Operational & value
33%
Price per mg, shipping, packaging, payment safety, and website trust signals.
Reputation & transparency
24%
Sampled community sentiment, disclosure of identity and testing, and our editorial judgement.
Independent
Grades are editorial. Verifying confirms facts — it never buys a higher grade.

Evidence-backed
