What is — Glutatión
Glutathione (GSH) is a low-molecular-weight tripeptide formed from L-glutamate, L-cysteine and glycine, and one of the most abundant endogenous antioxidants found in living cells. Peptworks supplies it as a lyophilized 600 mg research reagent in single vials, sold to businesses either as unbranded bulk or as white-label boxed product. It is a laboratory reagent for Research Use Only (RUO): it is not a medicine, supplement, cosmetic or medical device, and it is not intended for human or animal consumption.
In cellular research models, glutathione functions primarily through the reactive thiol (-SH) group of its cysteine residue. It cycles between a reduced form (GSH) and an oxidized disulfide form (GSSG), a couple widely used as an indicator of intracellular redox state. As a substrate for glutathione peroxidases it participates in the neutralization of peroxides, and as a substrate for glutathione S-transferases it participates in phase II conjugation pathways studied in detoxification models. It is also studied for its role in regenerating other antioxidant molecules such as ascorbate and tocopherol within in-vitro systems. All descriptions here refer to biochemical behavior observed in laboratory research, not to effects in humans.
Research
- Redox homeostasis and oxidative-stress assay development in cell culture
- Detoxification and phase II conjugation pathway research (glutathione S-transferases)
- Mitochondrial function and reactive-oxygen-species research models
- Cellular senescence and longevity research in vitro
- Hepatocyte and detoxification model systems
- Reference/standard material for analytical HPLC method work
Advantages
- Serves as a well-characterized reference antioxidant substrate in in-vitro redox assays
- Supports controlled study of the GSH/GSSG redox couple in cultured cells
- Useful as a comparator compound in oxidative-stress and free-radical research models
- Provides a consistent ≥98% HPLC-purity input for reproducible laboratory experiments
- Enables preclinical investigation of glutathione-dependent enzyme pathways
Safety
- Reductive stress or shifted redox tone has been reported in some cell-culture models exposed to elevated intracellular glutathione
- Oxidation to GSSG on exposure to air or improper reconstitution can alter assay results
- Reported cytotoxicity thresholds vary by cell line and concentration in preclinical models
- As with any thiol reagent, purity and storage conditions materially affect experimental reproducibility
Ideal for
- Laboratories developing oxidative-stress and redox assays
- Longevity and cellular-senescence research programs (in vitro)
- Detoxification-pathway and enzyme-kinetics studies
- Analytical labs needing a purity-defined reference reagent
- Resellers building a white-label longevity research-reagent catalog

Frequently asked questions
Where can I buy Glutathione in bulk in the EU?
Peptworks supplies Glutathione (600 mg lyophilized vials) as a B2B wholesale and white-label research reagent from stock already inside the EU. Orders ship intra-community in 3-5 business days with no customs. Minimum order is 10 units (one box) per reference; vials ship in boxes of 10. Research Use Only.
What is the wholesale price per vial for Glutathione?
Public per-vial pricing scales with your combined order volume: EUR 14.00/vial at 100 units, EUR 11.48/vial at 300 units (-18%), EUR 10.50/vial at 500 units (-25%) and EUR 9.52/vial at 1000 units (-32%). The discount is a single tier based on your combined total units across the order, not stacked.
Can I get Glutathione white-labelled with my own brand?
Yes. You can order plain unbranded vials in bulk, or white-label: vials labelled with your own brand and boxed. A one-time label setup fee of EUR 180 applies to orders under 100 units and is free from 100 units. Every box also carries the Peptworks label with a unique QR that links to that batch's CoA.
What is the minimum order for Glutathione?
The minimum order is 10 units (one box) per reference. Vials ship in boxes of 10, so quantities scale in multiples of 10. Volume discounts begin at the 100-unit combined tier.
How is the Certificate of Analysis (CoA) verified?
Each batch has an independent CoA covering HPLC purity (≥98%) and heavy metals. The box carries a unique QR code that links to that specific batch's CoA, verifiable through Peptworks, so your customers can confirm authenticity per lot.
How do I pay and how fast does it ship?
Payment is by USDC bank transfer / invoice; there is no card checkout on the site. Because stock is held inside the EU, orders ship intra-community in 3-5 business days with no customs clearance. The site is available in 10 languages (ES, EN, DE, FR, PT, IT, NL, PL, CS, EL).
