Glutathione 1500mg

Yes. Glutathione is a tripeptide — three amino acids, glutamate, cysteine and glycine, joined by peptide bonds. It is unusual in that the bond between glutamate and cysteine is a gamma linkage rather than the standard alpha peptide bond, which is part of why it resists breakdown by most peptidases. So it is genuinely a peptide, just a very short and slightly unusual one.

Glutathione 1500mg refers to the quantity of lyophilised glutathione powder in the vial, not a prepared solution. PhaseOne supplies it in the reduced (GSH) form for laboratory research into oxidative stress, redox signalling and detoxification pathways.

Reduced glutathione (GSH) is the free-thiol form; oxidised glutathione (GSSG) is two GSH molecules joined by a disulfide bond. The ratio between them is a standard laboratory marker of cellular redox state, so which form a supplier ships matters for research design. PhaseOne supplies the reduced GSH form.

PhaseOne ships glutathione Australia-wide for research use, dispatched locally with tracking, in 1500mg vials. Every vial carries a batch-specific Certificate of Analysis verifying ≥99% HPLC purity, so Australian researchers are not relying on overseas listings or unverified stock.

Yes — PhaseOne has glutathione for sale online in 1500mg vials, shipped Australia-wide. Listings vary considerably, since consumer glutathione supplements, oral tablets and research-grade lyophilised powder are different products. PhaseOne supplies research-grade reduced glutathione with a batch Certificate of Analysis.

PhaseOne prices glutathione at A$95.19 for a 1500mg vial, reduced from A$118.99, with the batch Certificate of Analysis included at no extra cost. Current pricing is shown on this page.

Chemist Warehouse and other Australian pharmacies do stock consumer glutathione supplements — oral capsules and tablets sold as complementary medicines. Those are a different category from research-grade material: different form, different purity specification, and no batch HPLC Certificate of Analysis. PhaseOne supplies lyophilised research-grade glutathione, which pharmacies do not carry.

Glutathione is among the most extensively studied endogenous compounds in cell biology. Published research has examined its role in redox homeostasis, reactive oxygen species handling, glutathione peroxidase and S-transferase enzyme systems, and phase II detoxification pathways. The GSH to GSSG ratio remains a standard laboratory measure of cellular oxidative state.

Glutathione is supplied as a lyophilised powder for improved stability during storage and shipping across Australia. Unreconstituted vials should be kept refrigerated and protected from direct light, and are commonly reconstituted using bacteriostatic water prior to research preparation. Reduced glutathione is particularly sensitive to oxidation once in solution, so prepared material is best kept cold and used promptly. (!) Read our reconstitution guide or bacteriostatic water guide.

As interest in research peptides grows across Australia, transparency and third-party testing have become increasingly important to Australian peptide buyers. All PhaseOne research peptides are supported by third-party HPLC testing, verified COA reporting, research-grade manufacturing standards, and Australia-wide access. (!) View our COA library.

HPLC testing refers to High Performance Liquid Chromatography, an analytical method used to verify peptide purity and compound identity - a standard PhaseOne applies to every research peptide sold in Australia.

Yes - glutathione is frequently studied within the same broader cellular and mitochondrial research category as other redox and metabolic compounds, including NAD+, SS-31 and MOTS-C. (!) View the full PhaseOne research range.
