We are very happy to introduce OPITAC Glutathione's new and unique sciences in our OPITAC website

This research informs the broader peptide-metal-complex field, including investigations of analog HGK:Cu (223-fold higher SOD-mimetic activity) and copper-binding PIP-tides.[3] Ferritin Iron-Blockade and Lipid Peroxidation Research Cell-free and cell-culture investigations use GHK-Cu to probe whether copper-tripeptide complexes can prevent iron release from ferritin and downstream membrane lipid peroxidation
