GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). Copper is held by three nitrogen donors — the glycine amino group, the Gly-His peptide nitrogen and the histidine imidazole — while the lysine side chain remains free. The complex is widely used as a reference compound in cell-culture and gene-expression studies.

Copper(II) sits in a square-planar arrangement, bound by three nitrogen atoms from the glycine and histidine residues; a fourth position is typically taken by water. Because GHK holds copper less tightly than serum albumin but more tightly than many low-affinity ligands, the complex is often used in laboratory models of copper exchange and transport.
GHK is the free tripeptide Gly-His-Lys. GHK-Cu is the same tripeptide bound to a copper(II) ion. This product is supplied as the copper complex.
