GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) first isolated from human plasma in 1973. This bioactive peptide demonstrates remarkable tissue regenerative properties, enhancing wound healing, collagen synthesis, and cellular repair mechanisms. Research shows GHK-Cu modulates expression of over 30% of human genes, promoting tissue remodeling while suppressing inflammatory pathways. The peptide increases collagen production by up to 70%, accelerates wound healing by 30-50%, and reduces wrinkle depth by 33%. GHK-Cu levels decline from 200 ng/mL at age 20 to 80 ng/mL by age 60, correlating with decreased regenerative capacity. Studies demonstrate improvements in skin density, hair follicle enlargement, and DNA repair gene activation, making it valuable for anti-aging applications and tissue restoration.
