GHK Cu and Inflammatory Based Diseases: Promising Avenues in Scientific Research World Of Peptides Exploring the mechanics of GHK Cu. Preclinical data indicates that this endogenous copper binding tripeptide (Glycine Histidine Lysine) interacts heavily with cellular signaling pathways. In controlled laboratory settings, researchers are observing its GHK Cu is a powerful copper peptide that supports collagen production, skin and hair health, and tissue repair. It may help reduce fine lines, improve elasticity, and promote faster healing.
