Testing: Labs & Certificates of Analysis
Instant Peptides publishes 248 certificates on its lab-tests page, from Freedom Diagnostics, Kovera Labs, Ethos Analytics and Vanguard Laboratory. Every one Prof. Peptide could read on October 17, 2026 names Instant Peptides as the client. The site itself names Ethos Analytics and Kovera Labs as its testing laboratories.
Prof. Peptide drew two Freedom Diagnostics certificates at random and found each in Freedom's own records, which returned nothing for an invented code first; both lab copies were identical to the store's. One is for its SS-31 10mg (99.72% purity) and one for its KLOW blend (99.76%).
Three things about the certificates, as read on October 17, 2026: the homepage says five vials per batch are tested, while most certificates list three or two vials; one AOD-9604 certificate carries the lot number the site gives its IGF-1 LR3; and the GLP-3 RT 15mg certificate prints a net content of 13.73 mg.
All products are sold for laboratory research use only.
