What Is GHK-Cu?
GHK-Cu (Copper Tripeptide-1) is a synthetic copper-binding tripeptide composed of the amino acid sequence glycine–histidine–lysine (GHK) complexed with a divalent copper (Cu²⁺) ion. The GHK peptide is naturally occurring in human plasma and tissues, and when coordinated with copper forms a stable bioactive complex suitable for controlled laboratory research environments.
