GHK-Cu (Copper Peptide) – Research Overview: Mechanisms, Gene Expression & Laboratory Application GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper) is a naturally occurring copper-binding tripeptide first isolated from human plasma in 1973. Present in blood, saliva, and urine, GHK-Cu levels decline significantly with age – from approximately 200 ng/mL at age 20 to around 80 ng/mL by age 60. This […]
