Storage & handling
Keep it stable, keep it sterile
Glutathione (γ-L-glutamyl-L-cysteinylglycine) is a tripeptide antioxidant present in nearly every cell, and the most abundant intracellular thiol in mammalian biology. It is central to redox homeostasis, phase-II detoxification, and melanogenesis regulation via tyrosinase inhibition. UK Peptides supplies reduced L-Glutathione (GSH) 1500mg as ≥98% HPLC lyophilised powder.

Published research on glutathione covers:
Store the lyophilised glutathione powder at -20°C, sealed and protected from light. Reduced glutathione oxidises rapidly on exposure to air — keep vials tightly sealed and reconstitute immediately before use where possible. Refrigerate the reconstituted solution at 2–8°C and use within 14 days. For longer storage, aliquot and freeze at -20°C.
Every Glutathione 1500mg lot is independently HPLC-UV tested to ≥98% purity by an accredited independent laboratory, with mass-spectrometry identity confirmation against the published molecular weight of 307.32 Da (reduced form). The signed PDF Certificate of Analysis is supplied with every order.
Glutathione is particularly sensitive to poor storage — a vial oxidised in transit is analytically inferior before it reaches your bench. UK Peptides ships with insulated mailers and ice packs, dispatches same-day from Manchester and provides third-party HPLC verification on every batch confirming reduced-form purity at the point of dispatch.
The science, in depth
Mechanism, the published evidence and handling detail for Glutathione are covered in full in our research library — 6 referenced articles rather than a summary on a product page.
Glutathione (γ-L-glutamyl-L-cysteinylglycine, GSH) is a small tripeptide antioxidant found at millimolar intracellular concentrations in almost every mammalian cell. It is central to redox homeostasis, phase-II detoxification via glutathione S-transferases, and glutathione peroxidase-mediated peroxide detoxification.
