Glutathione — research compound

Glutathione (γ-L-glutamyl-L-cysteinyl-glycine) is a tripeptide and the main intracellular thiol antioxidant. It is used in research on redox biology and oxidative stress models.

  • Form: powder in a sealed glass vial (600mg or 1500mg)
  • Quality: every batch is third-party tested by HPLC before release. The batch reference and purity are shown above; full reports are in our COA library.
  • Storage: keep the sealed vial in a cool, dry place away from light; store frozen for long-term storage.

For laboratory research use only. Not for human or veterinary use.

Our Purity Promise

Every batch of Peptonia peptides is third-party lab tested before it ever reaches you. We stand behind that testing completely — so much so that we back it with a full money-back guarantee.

If you send your product for independent lab testing and it does not verify at 99%+ purity, we will refund your order in full, and we'll also cover the cost of your lab test.

That's how confident we are in what we sell. No hoops, no fine print — just clean, verified peptides, guaranteed.

Store lyophilized (unreconstituted) vials in a freezer at -20°C for long-term storage, or refrigerated at 2-8°C for short-term storage (up to several weeks), protected from light. Once reconstituted with bacteriostatic water, refrigerate at 2-8°C and use within 14-30 days for best stability. Avoid repeated freeze-thaw cycles and direct sunlight. For research use only — reconstitution and storage should follow standard laboratory protocols.

This product is sold strictly for laboratory research use only. It is not intended for human or animal consumption, ingestion, injection, or any other in vivo use, and it is not a drug, dietary supplement, or cosmetic. By purchasing, you certify that you are 18+, purchasing as or on behalf of a qualified researcher or institution, and that you assume full legal responsibility for compliance with your local laws.
