Glutathione 1500mg
Endogenous tripeptide antioxidant researched for cellular redox defense, hepatic conjugation pathways, and pigment regulation.
Mechanism
Functions as a fundamental intracellular thiol antioxidant that neutralizes reactive oxygen species and acts as an essential substrate in enzymatic detoxification and conjugation pathways.
Dosing
Laboratory protocols document an initial dose of 100 mg administered two to three times weekly.
Reconstitution
Reconstituting a 1500 mg vial with 7.5 mL of bacteriostatic water yields a working concentration of 200 mg/mL.
Storage
Store unmixed lyophilized vials at -20°C in a dry environment protected from light, and keep the reconstituted solution refrigerated at 2–8°C without freezing.

Dosing Chart
| Phase / Day(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Weeks 1–2 (initiation) | 100 mg (2–3× weekly) | 50 units (0.50 mL) |
| Weeks 3–8 (maintenance) | 200 mg (2–3× weekly) | 100 units (1.0 mL) |
| Weeks 9–12 | 200 mg (2–3× weekly) | 100 units (1.0 mL) |
Reconstitution Steps
- 1
Aspirate 7.5 mL of bacteriostatic water into a sterile syringe.
- 2
Introduce the diluent slowly against the inside glass wall of the vial to minimize agitation and foaming.
- 3
Gently rotate or roll the vial until the lyophilized cake is fully dissolved, avoiding shaking.
- 4
Record the preparation date and resulting concentration (200 mg/mL) on the label, and store between 2–8°C away from light.

Overview
Glutathione is a low-molecular-weight tripeptide composed of glutamate, cysteine, and glycine, serving as a primary endogenous antioxidant within mammalian biological systems. In laboratory settings, investigators examine its capacity to scavenge reactive oxygen species, regenerate secondary antioxidants like vitamins C and E, and maintain cellular redox equilibrium. Preclinical research frequently focuses on glutathione's vital role as a cofactor for antioxidant enzymes, particularly glutathione peroxidase, as well as its involvement in Phase II hepatic detoxification reactions where it conjugates electrophilic compounds. Experimental models explore how maintaining intracellular pools protects critical cellular architecture and mitochondrial efficiency against oxidative damage. While explored in diverse experimental applications ranging from cellular resilience to skin pigmentation modulation, non-clinical research protocols emphasize careful handling due to molecular susceptibility to oxidation. Synthetic or lyophilized peptide formulations require strict environment controls to maintain thiol group integrity during analytical investigations.
