Endogenous tripeptide thiol, sold for laboratory research.
Identity
Glutathione is a small molecule the body already builds on its own, made from three amino acids strung together, glutamate, cysteine, and glycine. Every cell makes it, and it is one of the main tools cells use to handle everyday chemical stress. Outside the body it is sold as an oral capsule, an IV drip, and a topical cream, most commonly marketed for its effect on skin tone.
Glutathione is a endogenous tripeptide thiol of 3 amino acid residues, molecular formula C10H17N3O6S, molecular weight 307.32 g/mol. SBz Industries sells it for laboratory research.
Research
In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.
Most modern research attention on glutathione as a supplement has centered on skin tone, pulled together in a 2025 systematic review of human trials. Individual randomized trials, including one in 60 healthy volunteers, have measured its direct effect on skin melanin readings. Far less published human research exists on other proposed uses.
review2025
A 2025 systematic review pulled together human trials on topical, oral, and IV glutathione for skin tone, including five randomized trials on oral glutathione, and reported topical and oral forms produced a drop in melanin readings while IV glutathione showed no measurable change and was linked to more unwanted skin reactions.
Glutathione as a skin-lightening agent and in melasma: a systematic review.
Sarkar and colleagues, International Journal of Dermatology
people2012
Sixty healthy medical students took either oral glutathione or a placebo for four weeks, and researchers measured melanin index at six spots on the skin, finding a statistically real difference at two sites, the cheek and the sun-exposed forearm, compared with placebo.

Each study links to its record on PubMed, the US National Library of Medicine database. Checked 25 September 2026.
Handling
Lyophilized: -20C, protected from light. Reconstituted: 2-8C.
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
Slowly, down the inside wall of the vial, never straight onto the powder.
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.
Documentation
An independent lab tests every compound we sell. It confirms the compound is what the label says and measures purity by HPLC.
The latest certificate is on the product page, so you can read the result before you order.

Questions
Glutathione is a small molecule the body already builds on its own, made from three amino acids strung together, glutamate, cysteine, and glycine. Every cell makes it, and it is one of the main tools cells use to handle everyday chemical stress. Outside the body it is sold as an oral capsule, an IV drip, and a topical cream, most commonly marketed for its effect on skin tone. SBz Industries sells it for laboratory research only.
Human trials have looked at this directly. A 2012 study of 60 people found a small but statistically real drop in melanin index at some skin sites after oral use for four weeks, compared with placebo.
A 2025 review of the human trial evidence found IV glutathione showed no measurable effect on skin tone and was linked to more unwanted reactions than the oral or topical forms.
The molecular formula is C10H17N3O6S. The molecular weight is 307.32 g/mol. Both are stated on the certificate of analysis on the product page.
Glutathione ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.
Lyophilized: -20C, protected from light. Reconstituted: 2-8C. Vials ship in plain outer packaging with no product name on the outside.
Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.
Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
