GHK-CU

GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex) is a naturally occurring copper-binding tripeptide identified in human plasma, saliva, and urine. In research settings, it has been studied for its role in tissue remodeling, wound healing, and gene expression modulation.

Preclinical studies suggest GHK-Cu may influence collagen synthesis, angiogenesis, and inflammatory signaling pathways, as well as support extracellular matrix regulation. It has also been investigated in dermatological research related to skin regeneration and hair follicle biology.
