GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring human plasma tripeptide that declines sharply with age — from ~200ng/mL at age 20 to ~80ng/mL by age 60. It acts as a potent tissue remodeling signal, activating genes involved in collagen/elastin synthesis, antioxidant defenses, and anti-inflammatory responses. Loren Pickart's pioneering research identified it as a master regulator of tissue repair.
GHK-Cu binds copper(II) ions and delivers them to tissues where copper-dependent enzymes (lysyl oxidase, superoxide dismutase) require them. It activates TGF-β signaling for collagen synthesis, upregulates decorin and other proteoglycans for matrix remodeling, and downregulates TNF-α and IL-6. Genome-wide analysis shows it modulates over 4,000 human genes, including tumor suppressor pathways.
