GHK-Cu is the copper(II) coordination complex of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), a sequence originally isolated from human plasma. The GHK ligand chelates Cu²⁺ with high affinity; the complex is studied as a copper-delivery species and modulator of gene expression, extracellular-matrix enzymes and collagen synthesis in fibroblast cultures. It is a metallopeptide complex rather than a free linear peptide.
For laboratory research use only. Not for human or veterinary use.
