Testing: Labs & Certificates of Analysis
Licensed Peptides publishes a lab-report database with a permanent page for every lot, covering purity, endotoxin, heavy-metal and residual-solvent reports, and the QR code on each vial opens its lot's record. Licensed Peptides states that every batch it offers comes with a certificate of analysis.
Vanguard Laboratory, which issues most of the reports, lists 71 Licensed Peptides reports in its own public report store. Reports drawn from the store's database were checked at Vanguard's own report store on 9 October 2026, after it refused an invented report number, and every field matched. Vanguard's reports cover chromatographic purity and quantity by HPLC, and many add identity, endotoxin, sterility, heavy metals, residual solvents and TFA. The database also holds five earlier reports from Janoshik, which were not checked at the lab.
Finnrick rates Licensed Peptides 73% across 4 tests (read 9 October 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.
All products are sold for laboratory research use only.
