Glutathione (1.5 g) is a tripeptide antioxidant research compound studied for cellular redox balance, oxidative stress, and detoxification pathways. Third-party tested at 99% purity with a batch-specific COA. Ships across Canada. For research use only — not for human consumption.
Glutathione (GSH) is a naturally occurring tripeptide research compound composed of three amino acids — glutamic acid, cysteine, and glycine — studied in laboratory settings for its role in cellular antioxidant and redox signaling pathways. Each vial from Central Peptides contains 1.5 g of high-purity reduced glutathione, third-party verified and supplied with a batch-specific Certificate of Analysis (COA) for research use only. As one of the most studied antioxidant compounds in cellular biology, glutathione remains a frequently requested research material among Canadian laboratories.
Glutathione Research Applications
Glutathione is investigated in controlled laboratory environments as the predominant non-protein thiol found in animal tissues and physiological fluids. Research focuses on its role in cellular redox balance, oxidative stress models, and detoxification pathways. As a tripeptide containing a reactive thiol (-SH) group, glutathione is studied for how it interacts with reactive oxygen species and forms conjugates with various metabolites.
In biochemical research, reduced glutathione (GSH) is also widely used as a laboratory reagent — for example, in protein purification protocols to elute glutathione S-transferase (GST)-tagged proteins from affinity columns. This dual relevance, both as a study subject and as a research tool, makes glutathione a versatile compound in cellular and molecular biology.
Common research areas where glutathione is examined include:
Cellular antioxidant and redox signaling pathways
Oxidative stress and reactive oxygen species models
Detoxification and xenobiotic conjugation research
Protein purification (GST-tagged protein elution)
Purity and Quality Verification
Every batch of glutathione sold by Central Peptides is manufactured under controlled synthesis and purification processes to ensure stability, consistency, and structural integrity for scientific research applications. Our compounds are independently tested and verified at 99% purity through High-Performance Liquid Chromatography (HPLC) and mass spectrometry.
Each order includes access to a batch-specific Certificate of Analysis, allowing researchers to verify identity, purity percentage, and testing details before use. This batch-level traceability is part of our commitment to transparency and quality control across our full research catalog. Researchers who require documented purity standards for their work can review the COA before and after purchase, ensuring every vial meets the same verified specification.
Glutathione is supplied as a lyophilized (freeze-dried) powder for maximum stability during shipping and storage. The solid form is stable, but glutathione in aqueous solution is readily oxidized in air, so the lyophilized powder should be kept sealed in a cool, dry environment away from light until use.
Once reconstituted for research, glutathione dissolves readily in water (approximately 50 mg/mL). Reconstituted material should be kept refrigerated, protected from light and air exposure, and used within an appropriate window to maintain consistency in research results, since the reduced form oxidizes over time once in solution.
Shipping Across Canada
Central Peptides ships glutathione and all research compounds across Canada in discreet, temperature-conscious packaging. Orders are typically processed within 24 hours and delivered within 3 to 5 business days. Free delivery is available on qualifying orders over the threshold listed at checkout.
As a Canadian-based supplier, we offer domestic fulfillment, which means faster delivery times and fewer customs complications compared to ordering from international sources. Every shipment is packaged to protect the compound during transit and to maintain privacy.
