Oxidative stress develops when reactive oxygen species exceed antioxidant and repair capacity

The Science-Soundbite Version Full name: Glycyl-L-histidyl-L-lysine-Copper(II) Structure: A three-amino-acid chain (glycine, histidine, lysine) that chelates a single copper ion Natural origin: Found in human plasma, saliva, and urinehighest levels in our teens and twenties Why Copper Matters Copper is an essential trace mineral for more than 30 enzymes responsible for: Collagen cross-linking (skin firmness) Mitochondrial energy production (cell vitality) Antioxidant defense (superoxide dismutase) By bonding copper to a peptide carrier, GHK delivers the mineral directly into target tissues without the toxicity risks of free copper ions
