About GHK-Cu
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, first isolated from human plasma by Loren Pickart in 1973. It is one of the most studied copper peptides in cell and skin research.
Published work deals with collagen and glycosaminoglycan synthesis in fibroblasts and with gene-expression profiles in cell models.
