Every LA Peptides batch undergoes third-party testing to a minimum purity of ≥99%, and LA Peptides publishes a full batch-specific Certificate of Analysis library (at lapeptides.net/product-certificates/) issued by the third-party lab Bioviridian — though as of 27 September 2026 every path on the vendor’s domain, that library included, redirects to lapeptides.net/login/, so the certificates are no longer readable without an account — covering identity (LC-MS), purity (RP-HPLC at 214 nm), net content, endotoxin (USP <85>), heavy metals (USP <232>), and sterility (USP <71>), each result signed by the lab's principal chemist. Every certificate carries a per-record web verification code checkable at bioviridians.com/coa-search.html. Its peptides are sourced and manufactured within the United States under strict quality standards for research use.
Prof. Peptide checked Trustpilot and Finnrick on 30 September 2026.
