Glutathione
Not a peptide — small molecules & chemicals
Educational research guide only. To compare companies that offer Glutathione, open the Products page — scores belong to sellers, not this compound as a whole.
Glutathione (GSH) is a tripeptide antioxidant often stocked by peptide vendors. PurityWatch lists it as a research compound for seller comparison — not a peptide drug product and not medical advice.
Also known as: GSH · L-Glutathione · Reduced Glutathione · Reduced glutathione
What researchers mean by Glutathione
Glutathione is an endogenous tripeptide (γ-Glu-Cys-Gly) central to cellular redox chemistry. Research catalogs and compounding-adjacent sellers commonly offer reduced glutathione powder or vials. It is chemically a peptide, but PurityWatch groups it with small-molecule / non-“research peptide” catalog items when vendors market it alongside BPC-157-style products, so buyers can still compare COAs and trust signals without treating it as a typical synthetic research peptide.
Laboratory & catalog context
GSH oxidizes readily; transparent sellers disclose form (reduced GSH), assay method, and storage guidance. Compare batch COAs and vendor trust history on PurityWatch — we do not sell glutathione.
Common research focus areas
Reduced vs oxidized glutathione identity on COA
Assay method (HPLC, titration) and stated purity
Storage and oxidation sensitivity
Seller claims vs research-use-only labeling
Quality & transparency signals
Clear “reduced glutathione” labeling
Batch-specific assay / COA
Research-use-only language
Vendor complaint and review history
Compliance note
Glutathione discussed here is research-catalog context only. Not medical advice. PurityWatch does not sell compounds.
Companies on PurityWatch may list Glutathione as a compound they offer for research. Listing a compound does not mean it is approved for human use, and this entry is classified as not a peptide.
Glutathione is an endogenous tripeptide antioxidant. On PurityWatch it is classified separately from typical synthetic research peptides so you can still compare sellers without conflating product classes.
What should a COA show for glutathione?
Prefer batch identity as reduced glutathione (GSH), stated purity/assay method, and clear lot numbers matching the vial or bottle.
