Testing records
A COA shows the batch it names, not the lot shipped today. Vendors post certificates for specific batches; none of them shows which lot a vendor ships now, and a missing COA is shown as missing.
36 tracked offers for Melanotan II from 34 vendors: 27 have a public COA for the exact product and strength, 14 of them confirmed at the lab; 9 do not. The newest test date on file is Sep 16, 2026. Labs named: Accumark Labs, BioAnalytical Laboratory, Inc., BioRegen, Bioviridian, Chromate, Ethos Analytics and 9 more.
Each row is one vendor's offer for one exact product. It shows the report behind the testing state: for a lab-verified product the newest report the lab confirmed, otherwise the newest report on file. A lab link appears only where the lab confirmed the report. Every archived report is stored with its SHA-256 hash.
