Glutathione 1500mg
Glutathione (GSH, γ-L-Glutamyl-L-cysteinyl-glycine) is a naturally occurring tripeptide antioxidant composed of glutamic acid, cysteine, and glycine, with a distinctive γ-peptide bond between the glutamic acid side chain and cysteine. Glutathione is the most abundant intracellular thiol-containing peptide in mammalian cells and has been the subject of extensive cellular biology and biochemical research literature for over a century, with research contexts examining cellular redox biology, oxidative stress research, and thiol biochemistry.

Research Background
Glutathione has been investigated in research literature across several scientific contexts:
- Cellular redox biology
- Oxidative stress research — studies examining cellular response to reactive oxygen species (ROS) and the cellular glutathione system’s role in redox homeostasis
- Thiol biochemistry research — analytical chemistry studies on glutathione’s sulfhydryl group reactivity and protein S-glutathionylation in cellular research
- Cellular detoxification pathway research — studies on glutathione-S-transferase (GST) enzymatic systems and Phase II metabolism in cellular research models
- Mitochondrial cellular biology — research literature on mitochondrial glutathione pools and their role in cellular bioenergetics research
- Comparative thiol research — analytical studies positioning glutathione alongside other cellular thiol compounds in cellular research contexts
Glutathione is one of the most extensively characterized small molecules in cellular biology research, with foundational research spanning over a century of peer-reviewed publications across biochemistry, cellular biology, and analytical chemistry. The compound represents a foundational reference material in cellular redox research. Foundational research is available through PubMed (pubmed.ncbi.nlm.nih.gov) and the National Institutes of Health’s PMC database (pmc.ncbi.nlm.nih.gov), where researchers can access peer-reviewed studies on glutathione cellular biology and thiol biochemistry research.

Storage
Storage Instructions:
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
