Copper Tripeptide‑13%
The primary copper peptide in the formula.
Copper Tripeptide-1 is GHK-Cu, a copper peptide your body already makes. It was first isolated from human plasma in 1973. In lab research it increases collagen, elastin, and glycosaminoglycan production and supports the fibroblasts in the skin around each follicle. That’s the environment your hair grows from.
