Generic Peptides Glutathione 200 and 500 mg Research Vials

Generic Peptides Glutathione - 200 and 500 mg Research Vials

Generic Peptides Glutathione is GSH, the reduced tripeptide built from glutamate, cysteine and glycine, supplied as a lyophilized powder in 200 mg and 500 mg vials. It is the body's main water-soluble antioxidant and a cofactor in hepatic conjugation of xenobiotics, which is why it appears in oxidative-stress and liver-protection research rather than in hormone work. Buy Glutathione in the size that matches your design, and keep in mind that the clinical literature describes infusion and inhalation routes, while these vials are laboratory material.

• Two vial sizes - 200 mg and 500 mg
• Reduced tripeptide gamma-glutamyl-cysteinyl-glycine
• Lyophilized powder, needs bacteriostatic water
• GMP-made, HPLC-verified, COA on file

Variant Comparison

Both vials hold the same tripeptide and differ only in the amount of powder.

At 200 mg in 2 mL the mix reads 100 mg/mL, so 10 units on a U-100 syringe is 10 mg; the 500 mg vial in 10 mL gives 50 mg/mL, where the same draw is 5 mg. The 500 mg size suits a design that needs repeated sampling. In antioxidant work it is usually studied next to the thymus fraction Thymalin, and in skin and hair designs the copper peptide GHK-Cu covers a different angle.

How Glutathione Works

Glutathione is a tripeptide of glutamate, cysteine and glycine, and it donates electrons, which neutralises reactive oxygen species and recycles other antioxidants. Its cysteine thiol group also conjugates drugs and metabolites in phase II liver detoxification. The pharmacology is short: exogenous GSH has a half-life near 10 minutes, and one study measured 14.1 +/- 9.2 minutes after an intravenous infusion, so levels fall quickly unless the material is replenished. Medical use in several countries is an intravenous adjunct in antioxidant therapy, while regulators warn that injectable glutathione for skin lightening has no supporting clinical trials and is unapproved for that purpose.

Reconstitution & Storage

Add bacteriostatic water down the vial wall and swirl; do not shake. Keep the sealed powder at 2-8 C, protect it from light, and hold the mixed solution at 2-8 C without freezing; the thiol group oxidises once in solution, so mix only what a study will use.

Dosage & Administration

There is no approved research protocol for these vials. The clinical literature covers intravenous infusion, and no human pharmacokinetics exist for the subcutaneous route, so every number here is arithmetic for reconstitution and not a dose. Redox read-outs pair well with the metabolic arm of a study, such as NAD+, but keep the two in separate groups. Work from your own vial arithmetic and record each figure as a reference rather than a recommendation.
