GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine — a naturally occurring molecule found in human plasma, saliva, and urine. Plasma levels decline measurably with age, fueling decades of research into its role in tissue maintenance. It has been investigated extensively for collagen and elastin synthesis, antioxidant defense, modulation of inflammatory signalling, and recruitment of repair-relevant cell populations. GHK-Cu is supplied as the pre-formed copper(II) complex — no additional copper source is required for activity.
Key research areas
Widely studied for collagen and elastin synthesis, wound closure, and skin remodeling in vitro and in vivo.
Research indicates downregulation of pro-inflammatory cytokines and reduction of oxidative damage markers.
Investigated for effects on follicle size, anagen phase entry, and hair growth in dermatological models.
Studied for its ability to recruit immune and endothelial cells to sites of injury and modulate the extracellular matrix.

Store lyophilized peptide at −20°C, protected from light. Once reconstituted, store at 2–8°C and use within 14 days. Solutions may develop a deep blue colour — this is the characteristic copper(II) chromophore and is expected.
