Glutathione
An antioxidant made of three amino acids. It helps cells deal with chemical reactions and is used in lab research.

Why people look it up
Glutathione is a natural cellular antioxidant. It is discussed for oxidative stress, skin appearance, and broad 'detox' claims.
Skin pigmentationLIMITED HUMAN EVIDENCE
A small randomized study tested oral glutathione; it does not establish an effect for this dry vial. Read source ↗
Cellular antioxidant functionMECHANISTIC / LAB EVIDENCE
Cell experiments show glutathione's role in handling oxidative stress; this is not proof that added glutathione improves health outcomes. Read source ↗
General detox or energy boostINSUFFICIENT EVIDENCE
These broad outcomes were not established by the oral skin trial. Read source ↗

What the account says: A commenter described using a ready-made solution, not a dry vial, and reported intramuscular administration every other day. Glutathione is not itself a peptide.

Evidence, sources & vial math
What the research actually showsHuman studies, evidence limits and mechanisms
What has actually been studied?
Human skin studies used oral glutathione, while the listed material is a dry research vial. Biological antioxidant function does not by itself establish an anti-aging or detox treatment benefit.
Evidence limits: Effects vary by formulation and route; evidence for a skin or wellness claim does not establish outcomes or preparation for this vial.
Product status: Research-vial listings are not FDA-approved medicines. Approved-use labels on this page refer only to the named finished prescription product.
Human research
Oral glutathione and skin melanin index 2010
What was found: Compared with placebo, the melanin index fell significantly at two of six measured sites; this does not establish a broad skin or health benefit.
Main limit: Short trial in healthy students using oral capsules. Results cannot be transferred to an injected dry vial, and long-term safety was not established.
Study setup and amounts

- Otherwise healthy medical students in Bangkok
- Number of participants
- 60
- Study design
- Randomized, double-blind, placebo-controlled trial
- Route
- Oral capsules
- Amount studied
- 500 mg total per day in two divided doses
- Frequency
- Daily
- Duration
- Four weeks
- Outcome measured
- Melanin index at six body sites and UV spots
Study and prescription-product amounts describe those sources. They do not select an amount for an online research vial.
How researchers think it might work
Glutathione is a molecule cells already make and use in chemical reactions that help handle oxidative stress. Its normal cellular role does not prove that an injected research vial improves health or skin.
Show scientific explanation
Glutathione is a substrate in glutathione-peroxidase-dependent peroxide handling. In a human breast-cancer cell experiment, greater GPx-1 expression changed tolerance to oxidative stress; this is a cellular mechanism, not a clinical efficacy result for supplemental glutathione.

Vial & syringe math
Change the vial total and final liquid volume to see what each U-100 syringe mark represents.
The starting 1 mL is a math example. Enter your final mixed volume to update the numbers.
100 U-100 syringe units = 1 mL. These results assume the labeled amount is evenly mixed through the final liquid volume.
