Oxidative Stress Regulation: The 2012 Antioxidant Gene Expression Study Pickarts 2012 analysis GHK-Cu May Prevent Oxidative Stress in Skin by Regulating Copper and Modifying Expression of Numerous Antioxidant Genes (DOI: 10.3390/cosmetics3010026, accessible via PubMed Central) addressed a mechanistic paradox: how can a copper-containing compound function as an antioxidant when copper ions are notorious Fenton reaction catalysts
The CAPTAIN traumatic brain injury protocol is the clearest example: 50 mL/day by IV for 10 days, followed by two additional 10 mL/day cycles of 10 days each, with neurorecovery assessed across the following weeks (Muresanu et al

This suggests that researchers can expect similar outcomes from either compound when using equivalent dosing approaches
Hair density improvements are usually visible at the 8-week mark but continue improving through a 16- to 20-week protocol
