Find the perfect vendor for you

Pick the peptide you want and where it should ship to. We surface the highest-rated vendors that match.

How the grade works

Every vendor is scored 0–100 across eight weighted trust factors. A vendor with no independent COA can’t score above a D; fabricated COAs are capped at F.

43%

Lab & Purity

Independent third-party COAs (e.g. Janoshik), measured HPLC purity, and accredited lab partners, verified, not vendor say-so.

31%

Trust & Service

Transparency and disclosure, reputation with real buyers, and the operational trust signals of a legitimate business.

26%

Value & Logistics

Fair pricing for what you actually get, reliable shipping and fulfilment, and safe payment options at checkout.
