GHK
Copper-free form of the GHK tripeptide (glycyl-histidyl-lysine) used in cosmetic and skin research.
What is GHK?
GHK is the tripeptide glycyl-L-histidyl-L-lysine without bound copper. It occurs naturally in human plasma and binds copper readily, forming GHK-Cu.
Most published skin and wound-healing research concerns the copper complex rather than the free peptide.
