Glutathione is the tripeptide Glu-Cys-Gly and the dominant intracellular antioxidant. Its free thiol group drives redox cycling between reduced (GSH) and oxidized (GSSG) states, the standard readout of cellular oxidative status.
Reference data researchers look up before ordering glutathione. Every lot ships with documentation matching the batch number printed on the vial.
Each glutathione lot is released only after an independent purity panel. HPLC quantifies purity, LC-MS confirms molecular identity, and the lot-matched certificate is published so the number on your vial matches the report you download.
Glutathione ships lyophilized. Reconstitute with bacteriostatic water containing 0.9% benzyl alcohol. The ratios below assume a standard U-100 insulin syringe.
PX1 Research synthesizes and fills glutathione in a US cGMP-compliant facility rather than reselling imported material, so purity documentation traces back to the production lot. Multi-vial pricing steps down at 3, 5 and 10 vials, and subscription intervals are available on the product page.

10 mg + 2 mL = 5 mg/mL. A 250 mcg dose = 5 units on a U-100 syringe (40 doses per vial).

GSH is the reduced, active form; GSSG is the oxidized dimer. Their ratio is the standard measure of cellular redox balance.
10mL gives 150mg per mL, the most commonly cited working concentration.
Yes. Every glutathione lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.
Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
