GHK-Cu

GHK-Cu is a tripeptide (glycine-histidine-lysine) with high affinity for copper (II) ions. The GHK-Cu complex activates over 4,000 human genes through copper-mediated enzyme activation, transcription factor modulation, and direct receptor interactions. It naturally occurs in plasma, saliva, and urine at declining levels with age.

GHK-Cu activates superoxide dismutase, increases collagen, elastin, and glycosaminoglycan synthesis, promotes wound contraction via fibroblast activation, stimulates nerve outgrowth, suppresses IL-6 and TNF-α, and promotes hair follicle enlargement and anagen phase extension.

Research documents wound healing acceleration (complete closure 33% faster in wound models), hair follicle stimulation (significant increases in follicle size and hair shaft diameter), anti-aging effects on skin (reduced wrinkle depth, increased skin density), and neuroprotective effects. GHK-Cu is one of the most studied regenerative tripeptides.

Store lyophilized at -20°C or as copper complex solution at 2–8°C. Stable 60+ days at 2–8°C in solution. Protect from light.
