L-Glutathione

About L-Glutathione

L-Glutathione is a tripeptide composed of glutamate, cysteine, and glycine, and is one of the most abundant intracellular antioxidants in mammalian biochemistry. It appears extensively in research literature covering redox biology, detoxification pathways, and oxidative-stress models.

Laboratories use L-glutathione as a reference antioxidant in cell-culture systems, enzyme assays, and analytical redox studies. Its well-established chemistry also makes it a standard in spectrophotometric and chromatographic method development.

Pickering Peptides manufactures every batch to strict quality standards. Each lot is verified by independent third-party HPLC and mass-spectrometry testing at 99% purity or higher, then sealed as a lyophilized powder. Orders ship with tracking, and every order includes the batch report key so you can verify the lab results directly with the testing laboratory.
