Testing: Labs & Certificates of Analysis

6A Labs' certificate directory states 79 certificates across 44 products, from Freedom Diagnostics and ILS Laboratories. It lists 25 distinct Freedom Diagnostics search codes, and it marks 14 of its rows “Issued to the supplier, not to 6A Labs”.

Prof. Peptide drew three of the 25 Freedom Diagnostics codes by a seeded draw and looked each up at the laboratory's own lookup on October 27, 2026. All three drawn codes resolved at the lab, and each names 6A Labs as the client. The two retatrutide reports carry the lab-verified badge in the table below; the badge covers those two certificates, not the rest of the directory. The third report, for ARA-290 10 mg (lot 7767), prints purity of 99.58% and 99.52% by HPLC-UV, identity confirmed by LC-MS, a net content of about 9.95 mg, and passing endotoxin, microbial (PCR) and ICP-MS element results, with fentanyl not detected; it carries no badge because Prof. Peptide has no profile for ARA-290. The reports were not compared byte for byte with the vendor's copies.
