Anti-Aging and Epigenetic Repair Research shows that GHK-Cu can: Restore youthful gene expression profiles Reduce oxidative DNA damage Enhance antioxidant enzyme activity (SOD, catalase, glutathione peroxidase) It has become a cornerstone in peptide-based anti-aging protocols
Several studies suggest significant neuroactive properties: Anxiolytic effects: In a 2015 study, GHK-Cu injections led to more exploratory behavior and fewer freeze responses indicating reduced anxiety
