What Is GHK-Cu?

Tripeptide structure, copper coordination chemistry, and the 60% age-related decline

Three Amino Acids, One Copper Ion

GHK-Cu is one of the smallest biologically active molecules in your body -- just glycine, histidine, and lysine wrapped around a single copper ion. Despite its simplicity, this tripeptide-copper complex has a binding affinity so high it can steal copper from albumin, the most abundant protein in your blood.
