Glutathione is a naturally-occurring tripeptide composed of γ-glutamate, cysteine, and glycine. It is supplied as the reduced form (GSH) in lyophilized powder.
Glutathione is a foundational reference compound in preclinical antioxidant and redox-biology research.
Lyophilized under inert atmosphere. Reconstitute with sterile bacteriostatic water immediately before use; reduced glutathione is sensitive to oxidation and should be stored refrigerated and protected from light. For laboratory and research use only. Not for human or veterinary use.
Every batch of Glutathione is independently tested by a third-party laboratory. Certificates of Analysis include HPLC purity testing, mass spectrometry confirmation, and sterility verification.
