Glutathione

A tripeptide (glutamate–cysteine–glycine) naturally produced primarily in the liver, often called the body's “master antioxidant.” Neutralizes reactive oxygen species and supports the body's detoxification pathways.

Oxidative stress reduction and, in cosmetic use, skin-tone research — one of the more mainstream, well-characterized compounds in the catalog.

Lyophilized. Reconstitute with bacteriostatic water per the general reference below.

General reconstitution & storage reference for lyophilized peptides:

1. 1Reconstitute with bacteriostatic water (0.9% benzyl alcohol) rather than plain sterile water — the preservative meaningfully extends usable shelf life.
2. 2In bacteriostatic water, refrigerate at 2–8°C, typically usable for ~28–30 days. In plain sterile water (no preservative): 7–14 days.
3. 3Lyophilized (unmixed) vials are stable at refrigerated or, for some peptides, frozen temperatures for extended periods prior to reconstitution.
4. 4Avoid repeated freeze-thaw cycles, direct light/UV exposure, and heat — these are the primary drivers of peptide degradation.
5. 5Reconstitute gently: inject the water down the inside wall of the vial and swirl — don't shake, which can denature the peptide structure.

General handling precautions apply.
