Mechanisms of Action GHK-Cu interacts with multiple biological systems: Gene Modulation Regulates expression of over 4,000 genes Activates genes related to collagen production , antioxidant defense , and DNA repair Suppresses genes involved in inflammation , fibrosis , and tumor growth Tissue Remodeling Stimulates fibroblast activity for collagen and elastin synthesis Enhances wound contraction and angiogenesis Reduces scar formation Neuroprotective Effects Supports repair in nervous tissue Reduces oxidative stress in neurons Muscle and Connective Tissue Repair Increases glycosaminoglycan production Promotes myofibroblast differentiation If youre considering GHK-Cu as part of a recovery plan, structure matters
