GHK-Cu is a tripeptide (glycyl-histidyl-lysine) that forms a 1:1 complex with copper(II) at physiological pH. GHK-Cu was first identified in human plasma in 1973 by Dr. Loren Pickart and has since become one of the most extensively characterized matrix-remodeling peptides in dermatological and wound-biology research.
GHK-Cu has been shown in published literature to modulate gene expression of over 4,000 human genes — primarily related to collagen and elastin synthesis, metallothionein-driven antioxidant response, and anti-inflammatory cytokine profiles. Its copper-binding properties enable redox-active signaling in extracellular matrix remodeling.
Its discovery emerged from research into why plasma from younger donors appeared to enhance liver tissue repair. Since then, GHK-Cu has been characterized in 100+ peer-reviewed studies covering skin, hair, and extracellular matrix biology.
