How This Works
GHK-Cu functions as a “signal peptide” that triggers tissue repair processes by chelating copper(II) ions and delivering this essential trace metal to cells in a bioavailable form[1][9]. Copper is a critical cofactor for enzymes involved in collagen synthesis (lysyl oxidase) and antioxidant defense (superoxide dismutase). Genomic studies show GHK-Cu modulates over 30% of human genes toward a regenerative, anti-aging phenotype[2][10]. The peptide stimulates production of VEGF and bFGF in fibroblasts, promoting angiogenesis and blood flow to injured tissue[3]. GHK-Cu also recruits immune cells to injury sites, increases collagen/elastin/glycosaminoglycan synthesis, and regulates matrix metalloproteinases for balanced tissue remodeling[2][4].
