What Is GHK-Cu?
GHK-Cu (Copper Peptide) is a naturally occurring copper-binding peptide made of three amino acids: glycine, histidine, and lysine. It was first discovered in human plasma and is now widely used in anti-aging skincare, hair restoration products, wound healing research, and regenerative wellness therapies.
The peptide is especially popular because of its ability to support:

Today, GHK-Cu is one of the fastest-growing peptides in the cosmetic and wellness market.
