Glutathione -  1500 MG

Glutathione is an endogenous tripeptide first characterized by Frederick Gowland Hopkins in 1921, and is now recognized in the literature as the body's primary intracellular antioxidant.

Each vial ships with 1,500mg of Glutathione in lyophilized powder form for reconstitution, sealed for research use, backed by Phantom Peptides' internal verification standard: independent third-party lab analysis.

Product Specifications

  • Compound: Glutathione (L-Glutathione, reduced form / GSH)
  • Class: Endogenous tripeptide (antioxidant)
  • Sequence: γ-Glu-Cys-Gly (gamma-glutamyl linkage)
  • Molecular Weight: ~307.32 Da
  • Form: Lyophilized powder (for reconstitution)
  • Bottle Size: 1,500mg per vial

Research Background

The existing literature on glutathione spans a handful of distinct research threads:

  • Redox biology research: cell and animal model studies examining the GSH/GSSG ratio and glutathione's role in maintaining intracellular redox homeostasis
  • Detoxification research: studies on hepatic phase II conjugation and glutathione's role in xenobiotic and heavy metal clearance pathways
  • Immune function research: cell studies examining glutathione's role in lymphocyte proliferation and immune cell regulation
  • Mitochondrial and oxidative stress research: studies on mitochondrial glutathione pools in models of oxidative damage and cellular senescence

Glutathione's status as the primary endogenous antioxidant has made it a mainstay of biochemistry, toxicology, dermatology, and gerontology research literature. For primary sources, PubMed (pubmed.ncbi.nlm.nih.gov) and NIH's PMC database (pmc.ncbi.nlm.nih.gov) index the peer reviewed literature on glutathione and related antioxidant research.

Important Notice

Phantom Peptides supplies Glutathione strictly for laboratory research. It is not intended for human or veterinary use, and no dosage or administration guidance is provided. Any discussion of biological activity refers only to published preclinical or in vitro research.

Research questions

Frequently Asked Questions

1. Is Glutathione supplied as a lyophilized powder?

Yes. Glutathione ships as a lyophilized (freeze-dried) powder, which removes moisture and helps keep the compound stable until it is reconstituted for research.

2. How is the purity of Glutathione verified?

Each batch is tested by an independent laboratory using HPLC for purity and mass spectrometry for identity. The certificate of analysis for the current batch is linked on this page.

3. What does 99%+ HPLC purity mean?

High-performance liquid chromatography separates a sample into its components. A 99%+ result means the target compound makes up at least that percentage of the measured sample.

4. How should Glutathione be stored before reconstitution?

Keep the sealed vial at or below 8 °C in a dry place, away from light. For long-term storage, keep it frozen at −20 °C.

5. How long is Glutathione stable after reconstitution?

Refrigerated at 2–8 °C, use within 30 days. For longer preservation, aliquot and freeze at −20 °C and avoid repeated freeze–thaw cycles.

6. Can I see the COA before I order?

Yes. The full COA is available to download in the Certificate of Analysis section above, and on our COA page.

7. Is Glutathione intended for human use?

No. Glutathione is sold for laboratory research use only. It is not for human or veterinary consumption, and we do not provide dosage or administration guidance.

8. Where do orders ship from?

All orders ship from Charleston, SC with tracking.
