GHK-CU
GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. The copper(II) complex modulates extracellular matrix remodeling through stimulation of collagen synthesis, glycosaminoglycan production, and growth factor signaling. Research also examines its antioxidant activity through superoxide dismutase-like effects.
