GHK-Cu is a tripeptide with the amino acid sequence glycyl-L-histidyl-L-lysine. It occurs naturally in the human body, but its levels decline sharply by the age of 60. This decrease in GHK levels corresponds with a noticeable reduction in the body's regenerative capacity. The copper complex of GHK (GHK-Cu) has been shown to possess antioxidant, anti-inflammatory, regenerative, and wound-healing properties. Recent studies suggest that the GHK tripeptide can upregulate and downregulate a large number of human genes, which may contribute to the health-promoting effects of its copper complex.
