Antioxidant and Oxidative Stress Pathways A recurring theme across Epitalon cellular aging studies is the peptides proposed interaction with cellular antioxidant defence systems, a pathway also explored through the GHK-Cu Peptide , for research including: Superoxide dismutase (SOD) activity Catalase and glutathione peroxidase expression Reduction of lipid peroxidation markers in laboratory models These pathways are relevant because oxidative stress accumulation is considered a fundamental contributor to cellular ageing across multiple experimental models

In a world without as many toxins and stress as we are facing, your glutathione production may be working just fine

Combining both peptides simultaneously may cause overlapping effects that reduce efficiency
