By PSR score, the published vendor score out of 10, built from lab testing, certificate verification, pricing, shipping, operating history and reviews under the rules on How We Rate. Equal scores are listed alphabetically. Price per mg and the certificate for AHK-Cu are shown but do not change the order, and affiliate status never does.
Why are some AHK-Cu vendors listed separately?
6 vendors carrying AHK-Cu do not meet our testing gate: third-party testing could not be established or independently verified. They are listed below the ranking rather than in it. The gate records what we could verify; it is not a finding of a quality or safety problem.
How do I check a AHK-Cu certificate of analysis?
Open the certificate from the vendor's row, confirm it names AHK-Cu and a batch, then look up the verification key on the testing laboratory's own site. 9 of the 16 AHK-Cu certificates we track were confirmed at the lab. Our guide on how to read a peptide COA walks through each field. For laboratory research use only.
