GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine with a copper ion). First identified in human plasma in 1973, it has since been studied extensively for its effects on skin remodeling, wound healing, collagen synthesis, and anti-inflammatory signaling. Research has shown GHK-Cu activates genes involved in tissue remodeling and suppresses genes associated with inflammation and tissue destruction.
