GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It functions as a signaling molecule that resets gene expression to a healthier state, upregulating genes involved in antioxidant defense, DNA repair, and tissue remodeling while downregulating inflammatory and tissue-destructive genes. It stimulates collagen synthesis, glycosaminoglycan production, and angiogenesis. The copper ion is essential for activating copper-dependent enzymes like lysyl oxidase (collagen cross-linking) and superoxide dismutase.
