GHK-Cu

Research Overview

GHK-Cu has accumulated a substantial body of published research over five decades. Studies have examined its effects on collagen synthesis, glycosaminoglycan production, and gene expression in various cell culture and animal models. Research published in journals including the Journal of Biological Chemistry and Wound Repair and Regeneration has documented its interactions with multiple biological pathways. A landmark gene expression study by Pickart and colleagues identified over 4,000 genes modulated by GHK-Cu in human cell lines, including genes associated with DNA repair, antioxidant defense, and stem cell markers. The peptide's copper-binding properties are central to its biological activity, as copper is a cofactor for numerous enzymes involved in tissue remodeling.
