GHK-Cu is a small copper-binding tripeptide (glycine-histidine-lysine) complexed with copper, found naturally in blood plasma. It is sold as a research chemical and in cosmetic contexts, not as an approved drug. Note that the CAS commonly filed for GHK-Cu (49557-75-7) actually identifies the copper-free peptide, so any listing should state clearly whether it refers to the peptide or the copper complex.
The CAS commonly filed for GHK-Cu (49557-75-7) actually identifies the copper-free peptide GHK. The copper complex is a distinct substance — confirm from the COA whether a product is the peptide or the copper complex.
Regulatory status: GHK-Cu is not an FDA-approved drug; the copper tripeptide appears among bulk drug substances the FDA flags as possibly presenting significant safety risks (Category 2) for compounding, page content current as of 04/22/2026.
