The copper-peptide complex stimulates collagen and glycosaminoglycan synthesis, promotes angiogenesis, activates antioxidant enzymes including superoxide dismutase, modulates inflammatory responses, and stimulates hair growth through follicle activation
These effects are context-dependent and vary with concentration, exposure duration, and experimental system, making GHK-Cu a widely used molecular tool for investigating copper-mediated signalling and peptidemetal interactions in vitro and in vivo
