About GHK-Cu
GHK-Cu is a tripeptide composed of glycine, histidine, and lysine that naturally chelates a copper(II) ion, forming a stable copper-peptide complex. The copper-binding property is central to its activity and distinguishes it from non-metallated peptides, making it a widely studied molecule in matrix-remodeling and cellular-signaling research.
In laboratory contexts, GHK-Cu is investigated for its effects on collagen and extracellular-matrix models, skin and hair follicle research, antioxidant signaling, and tissue regeneration. It is supplied as a lyophilized powder for reconstitution under controlled conditions, tested to ≥98% purity with a certificate of analysis available on request. Offered for research use only.
