Glutathione 600mg is supplied strictly for laboratory research use only. This material is intended for analytical and controlled research applications. It is not approved or intended for human or animal use, ingestion, dosing, or therapeutic application.
Glutathione is a tripeptide (glutamate–cysteine–glycine) widely used as a reference compound in redox-biology and enzymology research. Published in-vitro literature has characterised it in the following experimental contexts:
Redox chemistry. The reduced (GSH) and oxidised (GSSG) forms are commonly quantified as a ratio in cell-culture models used to describe oxidative state. Interconversion between the two forms is catalysed by glutathione reductase.
Conjugation chemistry. Glutathione S-transferase enzymes catalyse conjugation of glutathione to electrophilic substrates, a reaction frequently used in enzymology and metabolite-identification assays.
Antioxidant cycling models. Its chemical interaction with ascorbate and tocopherol has been described in model systems.
Cell-signalling literature. Intracellular glutathione concentration is reported as an experimental variable in published lymphocyte and natural-killer-cell assay models.
Enzyme-inhibition literature. Interaction with tyrosinase has been described in in-vitro pigment-chemistry studies.
The material is produced as a high-purity research reagent under controlled conditions, with batch-level quality control to support reproducibility across laboratory studies.
This product is intended strictly for research and laboratory use only. Not for human or animal use. No statement on this page describes or implies any physiological, cosmetic, diagnostic, or therapeutic effect in humans or animals.

Antioxidant and redox activity
Glutathione is a major intracellular antioxidant that helps control reactive oxygen species and maintain cellular redox balance. Its reduced form (GSH) can be oxidized to GSSG and subsequently regenerated through the glutathione reductase system.”
Detoxification and glutathione S-transferases
Glutathione participates in cellular detoxification by serving as a substrate for glutathione S-transferases (GSTs). These enzymes facilitate the conjugation of GSH with various electrophilic compounds, helping the body process and eliminate certain endogenous and foreign substances.
Immune system support
Research indicates that intracellular glutathione contributes to normal immune-cell activity, including T-cell proliferation and other functions of innate and adaptive immunity. However, this does not necessarily mean that increasing glutathione above normal levels improves immunity in healthy people.
Role in melanogenesis and tyrosinase activity
Glutathione has been investigated for its effects on melanin production. Proposed mechanisms include modulation of tyrosinase activity and a shift in melanin synthesis toward pheomelanin. Clinical studies of oral and topical glutathione have reported some reductions in melanin measurements, although the available evidence is limited and the long-term effects remain uncertain.
Topical glutathione and skin pigmentation
A randomized, double-blind, placebo-controlled study involving 30 healthy Filipino women found that topical 2% oxidized glutathione was associated with reductions in measured skin melanin during the 10-week study period.
ALL ARTICLES AND PRODUCT INFORMATION PROVIDED ON THIS WEBSITE ARE FOR INFORMATIONAL AND EDUCATIONAL PURPOSES ONLY.
The products available on this website are intended solely for in-vitro research purposes (Latin: “in glass”), meaning they are used in experiments conducted outside a living organism. These products are not medicines or drugs, have not been evaluated or approved by the U.S. Food and Drug Administration (FDA), and are not intended to diagnose, treat, cure, or prevent any disease or medical condition. Any administration to humans or animals, whether by ingestion, injection, or other means, is strictly prohibited by law.
Our peptides are produced exclusively for laboratory and scientific research purposes.
Licensed Peptides™ products are developed using industry-standard synthesis and purification protocols, making them suitable for in vitro research, analytical testing, and experimental models.
Strict process controls ensure reproducibility, allowing researchers to work with confidence across experiments.
Our peptides are commonly used in research involving:
All products are intended for research use only and are not for human or animal consumption, therapeutic use, or clinical application.
At Licensed Peptides™, quality isn’t a claim. it’s a controlled, repeatable process.
Every peptide we produce follows a strict, pharma-grade workflow designed to ensure purity, stability, and consistency from synthesis to delivery.
All peptides are synthesized in sterile, controlled environments to eliminate contamination risk and ensure batch consistency.
We use advanced High-Performance Liquid Chromatography (HPLC) to separate and verify peptide purity with precision.
Each batch undergoes heavy metal and endotoxin screening to ensure it is free from hidden contaminants.
We start with rigorously tested amino acids and reagents, ensuring integrity at the molecular level.
Freeze-dried peptides maintain long-term stability, potency, and reliability for research applications.
Every vial is protected from oxygen and moisture, preserving structural integrity during storage and transit.
From synthesis to delivery, every step is engineered to meet the expectations of professionals who require accuracy, consistency, and reliability.
We understand that timing and product integrity are critical for research.
All in-stock orders placed before our daily cutoff are shipped the same day from within the United States.
We use expedited carriers to ensure your peptides arrive quickly and reliably nationwide.
Products are stored in industrial-grade freezers prior to shipment to maintain stability and purity.
Each order is carefully packed to protect against temperature fluctuations, moisture exposure, and physical damage during transit.
You’ll receive tracking information immediately upon shipment so you can monitor delivery progress.
No long international delays, no customs issues. Just fast, dependable delivery from a U.S.-based operation.
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.
