Emerging research suggests that copper peptides such as GHK-Cu may support collagen signaling, wound repair pathways, and anti-inflammatory activity, aligning with evidence informed anti-aging strategies
Critically, however, small amounts of ROS are necessary for healthy functioning as they are important intercellular signalling molecules: in large amounts though, ROS can be highly toxic because of their ability to react with sensitive intracellular biomolecules (DNA, proteins, lipids in bi-layer membranes, etc.) and so disrupt the vital biochemical pathways that sustain life [Morrell, 2010]
