GHK-Cu 99.9% Purity — HB PeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum, with the original poster claiming a lab tested HB Peptide's GHK-Cu. The report shows 99.927% purity via HPLC + MS, with a tested quantity of 111.49 mg against a 100mg label. However, the lab's signature is not directly verifiable, and the image has passed through at least one re-share, creating a chain-of-custody gap. This should be treated as community signal, not confirmation.
