Effects of bioactive tetrapeptides on free-radical processes
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
In this rat study, the authors report that injections of the tetrapeptides epithalon and cortagen decreased the content of lipid peroxidation products and reduced oxidative modification of proteins, and that this was paralleled by suppression of antioxidant activity in rat serum and cerebral cortex. The abstract is brief and provides no numerical figures for these changes.
Abstract
Injections of epithalon and cortagen to rats decreased the content of LPO products and reduced oxidative modification of proteins, which was paralleled by suppression of antioxidant activity in rat serum and cerebral cortex.
pepmg summarizes the peer-reviewed literature and links to every source. It sells nothing and ships nothing. Where an FDA label, a peer-reviewed study or a clinical-trial registry entry (labeled trial registry, not peer-reviewed) has published a dose, pepmg reports it with the source named; it gives no personalized recommendations and no administration technique. Don't just trust this summary: follow the citation to its source and read it yourself. Research use only.
