Glutathione 1500mg - the tripeptide gamma-glutamyl-cysteinyl-glycine, studied for redox buffering and phase II conjugation research.
Research Use Only:This compound is intended exclusively for in vitro laboratory research applications. Not for human or veterinary consumption.
Glutathione 1500mg research overview
Glutathione is a tripeptide of glutamate, cysteine and glycine, distinguished by an unusual gamma peptide bond at the glutamate residue that makes it resistant to most peptidases. It is the most abundant low-molecular-weight thiol in the cell, and its concentration is high enough that it functions as a redox buffer rather than merely a substrate.
Research uses it in two broad roles. The first is redox: the ratio of reduced glutathione to its oxidised disulfide form is a standard readout of cellular oxidative state, and glutathione peroxidase and glutathione reductase activity are measured against it. The second is conjugation - glutathione S-transferases attach it to electrophilic compounds as the first step of the mercapturic acid pathway, making it central to phase II metabolism and to xenobiotic handling studies. Separate work examines protein S-glutathionylation as a reversible post-translational modification, and glutathione depletion as a model of oxidative stress.
This listing supplies 1500mg of lyophilized powder, the largest single quantity in the catalog. It is grouped with B-12 under research-grade vitamin and antioxidant preparations. Glutathione oxidises readily in solution, so prepare working dilutions immediately before use rather than storing them, and keep the sealed vial refrigerated at 2-8 degrees Celsius. For laboratory research only. Not a dietary product and not for human or veterinary use.

Questions about this listing
- What form does Glutathione 1500mg come in?
Lyophilized Powder The size options listed on this page — 1500mg — are what is available, and the vial labelling shown in the product images above is the reference for what a vial contains.
- How should Glutathione 1500mg be stored?
Refrigerate at 2-8°C. Prepare dilutions immediately before use - oxidises in solution. Storage requirements differ across the catalog — some listings are refrigerated, others held at -20°C, others at room temperature — so read this row rather than assuming from a neighbouring product.
- Does Savage Labs supply a diluent for Glutathione 1500mg?
Bacteriostatic water is stocked separately in 3mL and 10mL vials. Savage Labs does not specify a reconstitution volume, a working concentration, or a basis for calculating either — those are determined by the protocol the material is used in, not by this catalog.
- What does the 99% figure on this listing mean?
It is the purity reported for this material. It is a reported value rather than one Savage Labs has independently verified for the lot you receive, and it does not describe net peptide content. How peptide purity is reported and net peptide content cover what the number does and does not tell you.
- What documentation is available for Glutathione 1500mg?
Batch-specific certificates of analysis and test methods on request. Confirm that any report matches the lot you intend to order — reading a peptide certificate of analysis covers which field answers which question. Ask about documentation for this listing, or see the full FAQ for ordering, shipping and returns.
- What else is grouped with Glutathione 1500mg?
It is catalogued under Vitamins & Wellness, where the category page describes what separates the compounds in the group.
Ordering, payment, shipping and returns are answered on the full FAQ.
