GHK-Cu 100.0% Purity — Jett LabsCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum/Discord channel. The original poster claimed a lab tested Jett Labs' GHK-Cu, reporting 99.958% purity via HPLC with UV Detection Coupled with Mass Spectrometry. The tested quantity was 55.79mg against a 50mg label, an 11.58% deviation. 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.
