Testing: Labs & Certificates of Analysis
99 Purity Peptides publishes a testing library (99puritypeptides.com/certificates) that lists each batch's product, purity, batch number and analysis date, with the certificate to download. It states that every batch is verified through independent third-party US laboratories by HPLC and mass spectrometry, to a minimum of 99% purity.
The certificates in that library are purity reports from Optiq Health Labs and Accurate Test Labs, and sterility and endotoxin reports from Eagle Analytical Services, each filed under a batch number. The Optiq Health Labs and Accurate Test Labs certificates name Wholesale Peptide Supply as the client.
What the laboratory shows. On October 21, 2026 Prof. Peptide drew three of the Optiq Health Labs certificates from the library at random and found each one at Optiq Health Labs’ own certificate system, with the same lot and results. All three name Wholesale Peptide Supply as the client; the panel below shows them exactly as the laboratory records them.
