This product is intended for laboratory and research use only. Not for human consumption.

Glutathione is a naturally occurring tripeptide (γ-L-glutamyl-L-cysteinyl-glycine) and one of the body's most important endogenous antioxidants, widely studied in preclinical research for its role in oxidative stress regulation, cellular detoxification, and immune modulation. Research has examined glutathione for its involvement in reactive oxygen species neutralization, xenobiotic metabolism, DNA repair, and mitochondrial function. Also studied in aging biology, neurological protection, and hepatic detoxification. PeptideBull supplies Glutathione at confirmed research-grade purity. Not intended for human or veterinary consumption.
