GHK-CU

GHK-Cu is a naturally occurring copper-binding tripeptide studied for skin remodeling, collagen signaling, wound-healing biology, hair-follicle research, and tissue regeneration. Copper peptides are of interest because copper is involved in enzymes that support extracellular matrix formation, antioxidant defense, and tissue repair. Researchers study GHK-Cu in models involving collagen production, elastin organization, inflammation response, skin firmness, hair growth environments, and wound recovery. It is one of the most recognized cosmetic and regenerative peptides because it connects trace-mineral biology with peptide signaling. It is frequently used in skin, hair, and repair research.
