Wholesale Reduced Glutathione (GSH) API

What Is Reduced Glutathione (GSH)?

Glutathione (γ-L-glutamyl-L-cysteinyl-glycine) is the most abundant intracellular antioxidant in the human body, present in virtually every cell at millimolar concentrations. The reduced form (GSH) is the biologically active species — it serves as the primary substrate for glutathione peroxidase enzymes that neutralize hydrogen peroxide and lipid hydroperoxides, and participates in phase II detoxification reactions that conjugate electrophilic toxins for hepatic excretion. GSH also directly scavenges reactive oxygen species (ROS), regenerates oxidized vitamins C and E, and maintains the redox balance essential for proper immune cell function, mitochondrial integrity, and cellular signaling. Glutathione levels decline with age, chronic illness, oxidative stress, and acetaminophen toxicity, creating demand for parenteral glutathione replenishment in clinical settings.

Medspas, IV therapy centers, and compounding pharmacies offering intravenous or subcutaneous glutathione protocols require pharmaceutical-grade material with sterility and endotoxin data. Wholesale Peptide Distributors supplies reduced L-glutathione (GSH) in the biologically active reduced form — not oxidized glutathione (GSSG) — with HPLC purity ≥98%, lot-specific endotoxin testing <1 EU/mg, and sterility testing for facilities compounding injectable formulations. Full CoA packages are available for all approved wholesale accounts. We do not supply oxidized or racemic forms without disclosure.

Glutathione is one of the highest-volume wellness compounds in the medspa and IV therapy market, with significant ongoing demand driven by skin brightening protocols, detoxification programs, and immune support IV drip menus. High-volume accounts ordering 500g+ per month receive the most competitive pricing tiers. Wholesale Peptide Distributors also offers glutathione in pre-filled sterile vials for facilities with limited compounding infrastructure, and can accommodate custom vial fill volumes for chains operating at scale.

When sourcing wholesale glutathione, it is essential to verify that your supplier provides documentation of the reduced form, not merely generic "glutathione" which may be partially oxidized. Our wholesale glutathione CoA includes specific confirmation of the reduced form via HPLC analysis with UV detection at 210nm and mass spectrometry confirmation. Apply for a wholesale account to receive current pricing, availability, and sample CoA documentation for your facility.
