Licensed Peptides states a 99%+ purity standard, and publishes batch-specific Certificates of Analysis issued by Vanguard Laboratory (Olympia, WA; ISO/IEC 17025:2017-accredited, A2LA 6377.01 — a certificate whose published A2LA scope covers microbiology, trace elements and residual solvents, and does not list HPLC or LC-MS purity or identity testing). Each report verifies chromatographic purity and quantity by HPLC-UV/VIS, with heavy-metal (ICP-MS), endotoxin (LAL), and sterility (USP <71>) screening; recent batch reports additionally carry residual-solvent (GC-MS) and trifluoroacetic-acid (ion chromatography) panels. A COA is published on each product page — linked directly as a merged multi-page PDF on the vendor’s own domain, with no login — and in a public purity-reports library. The vendor’s testing-methodology page names a second laboratory alongside Vanguard: Ethos Analytics (cert. 117798). Prof. Peptide has not opened an Ethos certificate, so that partner is reported as the vendor names it.
Licensed Peptides says it synthesizes its compounds in GMP-certified US facilities; it prices in US dollars and offers free FedEx shipping on orders over $200 with same-day US fulfillment. All products are sold for laboratory and research use only.
Finnrick rates Licensed Peptides 73% across 4 tests (read 30 September 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.
