GHK-CU

GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper-binding peptide composed of glycine, histidine, and lysine.

First identified in human plasma, it has since been found in saliva and urine. GHK-Cu has been studied extensively for its potential role in tissue regeneration, wound healing, and skin repair.

Its strong affinity for copper allows it to act as a carrier molecule, influencing numerous biological pathways.
