GHK-Cu

GHK-Cu is a naturally occurring tripeptide–copper(II) complex first isolated from human plasma. Formed from the tripeptide GHK (Gly-His-Lys) coordinated to a copper(II) ion, GHK-Cu is studied for its roles in tissue remodeling, wound healing, collagen biosynthesis, and antioxidant regulation. It is among the most extensively characterized copper-binding peptides in biomedical research, with documented effects on skin fibroblast proliferation, extracellular matrix gene expression, and hair follicle biology. Vitaconin supplies GHK-Cu as lyophilized powder at ≥99% HPLC purity with full COA documentation for research institutions, peptide manufacturers, and formulators worldwide.
