Vendor COA & Testing-Transparency Index
Last reviewed: June 2026
A structured, side-by-side record of what each research-peptide vendor publicly documents about its lab testing — third-party testing, Certificates of Analysis, purity standards, and testing methods. Every cell is drawn from the vendor’s own materials; nothing is inferred and no vendor’s claim is applied to another.
“Pending verification” means we have not yet confirmed that data point from a public source — it is not a negative judgment. Cells are filled only when verifiable. See how we compile and verify this data. All entries are for research-use-only context and are not medical advice. Affiliate relationships do not determine vendor inclusion, ranking, or verification — see our disclaimer.
