It is widely used in regenerative settings because it supports tissue repair across multiple systems, particularly connective tissue
Copper is essential for many enzymes responsible for: Collagen and elastin production (for firm, resilient skin and connective tissue) Antioxidant protection, including enzymes like superoxide dismutase (SOD) Cellular energy metabolism and repair processes GHK-Cu therefore helps regulate both the breakdown of damaged tissue and the formation of healthy new tissue, giving it importance in research on wound healing, anti-aging, hair growth, and even gene expression regulation
