L-Glutathione — specifically in its reduced form (GSH) — is a tripeptide (glutamate-cysteine-glycine) that serves as the primary intracellular antioxidant in mammalian cells. It's involved in neutralizing reactive oxygen species (ROS), supporting immune cell function, and maintaining the redox environment that cells depend on for normal metabolic activity. Its central role in cellular biology makes it one of the most widely studied compounds in antioxidant research.
Research has explored glutathione's role across multiple biological systems. Studies have investigated its function in detoxification pathways, its involvement in regulating apoptosis, and its interaction with other antioxidant enzymes like glutathione peroxidase and glutathione reductase. Reduced glutathione (GSH) is the active form — it can be oxidized to GSSG, and the GSH/GSSG ratio is commonly used as a marker of oxidative stress in research models.
Researchers also study glutathione in the context of mitochondrial function, immune system biology, and cellular aging, where declining intracellular GSH levels have been associated with increased oxidative burden in aging tissue models. Its involvement in phase II detoxification also makes it relevant to pharmacological and toxicology research.
myPEPT supplies L-Glutathione (reduced) at ≥99% verified purity with a Certificate of Analysis from independent lab testing. Shipped across the EU in sealed, research-grade packaging suitable for laboratory intake.

Frequently asked
7 questionsHow fast is delivery and which carriers do you use?
Orders placed before 16:00 CET ship the same business day from the Netherlands via DPD or PostNL. EU-wide delivery typically takes 2–5 working days, fully tracked. Every parcel ships in plain, unbranded packaging with no peptide-related markings visible.
Which payment methods do you accept?
We accept iDEAL (Netherlands), Bancontact (Belgium), PayPal, Klarna pay-later, SEPA instant bank transfer, and Visa/Mastercard credit and debit cards. All payments are processed through PCI-DSS-compliant European processors. Bank transfer and card orders ship within 24 hours of payment confirmation.
How do you verify peptide purity?
Every batch is HPLC-tested to 99% purity or higher by an independent third-party laboratory, with identity confirmed by mass spectrometry. The batch-specific Certificate of Analysis is published on every product page and delivered with the order.
Are research peptides legal to buy in the Netherlands and EU?
Yes — when sold and purchased strictly for in-vitro laboratory research. Research peptides on my\PEPT.eu are not approved, marketed or intended for human or veterinary use, medical diagnosis or therapeutic application. By placing an order you confirm research-only intent and accept responsibility for compliance with local regulations.
How should research peptides be stored?
Lyophilized (freeze-dried) peptides keep up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight.
What is Glutathione as a research compound?
Glutathione (L-gamma-glutamyl-L-cysteinyl-glycine) is a naturally occurring tripeptide antioxidant with a molecular weight of approximately 307 Da. As a research compound it is studied in laboratory settings for its role in cellular redox balance, enzyme cofactor function, and oxidative stress assays. The lyophilized form available from my\PEPT.eu is not for human or veterinary consumption — it is intended for laboratory research only.
How should Glutathione be stored?
Lyophilized Glutathione should be stored at −20 °C in a sealed, light-protected vial, as the thiol group is susceptible to oxidation. Once dissolved in buffer for laboratory assay use, use immediately or store briefly at 2–8 °C under inert gas if possible. Avoid repeated freeze-thaw cycles. Supplied for in-vitro research use only.
