Download COA (PDF)GHK-Cu (Glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper-binding tripeptide first isolated from human plasma. As one of the most extensively characterized copper-binding peptides in experimental biology, GHK-Cu has accumulated a substantial body of preclinical literature exploring its interactions with collagen and elastin synthesis signaling, matrix metalloproteinase (MMP) pathway regulation, and antioxidant enzyme activity mechanisms.
Current research investigates GHK-Cu across a range of biological systems, including dermal fibroblast models, collagen synthesis studies, wound healing pathway research, and hair follicle biology investigations. Studies conducted in controlled laboratory settings suggest notable activity in TGF-β signaling pathways and upstream collagen regulatory mechanisms, making it a compound of significant and sustained interest in extracellular matrix and skin biology research.
