Two audits, side by side. Composite, subscores, shipping, payment, coupons. Ion Peptide takes the higher composite this cycle.

Composite score

OF 100

VENDOR AUDIT

CertaPeptides

EU-based (Romania) research-peptide supplier that does the thing our rubric rewards — real third-party Janoshik COAs hosted on Janoshik's own public portal, with verifiable report IDs, real compound names, and an honest two-tier split between "independently tested" lots and "supplier batch specification" lots. The main caveats are scope and age — only about a third of the catalog has an independent report (the rest is a supplier ≥98% class spec, not a per-lot measurement), and the operation is new despite a "founded 2024" claim. Public-data preview; first-hand audit pending.

VENDOR AUDIT

Ion Peptide

US research-peptide vendor with the cleanest COA paper trail in our public-data cohort - 120 Kovera Labs reports across two months at a median 99.93% purity, zero failures, zero identity-mismatch. Coded ION-X SKU naming on a subset of products is worth knowing about.
