Testing: Labs & Certificates of Analysis
True Peptides' certificates are issued by Optiq Health Labs, LLC of Santa Ana, California, and its certificate database is searchable by lot number or product name. True Peptides states that each vial's label carries a lot number tied to a dated certificate for that lot, and that purity, sterility and residual solvent testing come standard with every batch.
On October 14, 2026 Prof. Peptide drew three certificates from the database, MOTS-c 10mg, Retatrutide 10mg and Tesamorelin 10mg, and found each one in Optiq Health Labs' own verify app by its certificate number.
