GHK-Cu is a copper-binding peptide that influences over 4,000 human genes. It stimulates collagen and elastin synthesis, enhances wound healing through angiogenesis and tissue remodeling, modulates MMPs and TIMPs, reduces inflammation by suppressing NF-κB and TNF-alpha, provides antioxidant effects by upregulating SOD and catalase, and supports hair growth by extending anagen phase.
