Glutathione Spray supplies reduced L-glutathione (GSH), chemical name gamma-L-glutamyl-L-cysteinyl-glycine, a tripeptide built from glutamate, cysteine and glycine with a free thiol on the cysteine residue. Its formula is C10H17N3O6S, molecular weight 307.32 g/mol, CAS 70-18-8, PubChem CID 124886. The oxidized counterpart, GSSG, is a chemically distinct molecule with roughly twice the mass and its own separate CAS number, so the exact form should always be confirmed on a lot’s documentation. Offered in 600 mg and 1500 mg spray-dispensed sizes for laboratory research use only.

Glutathione Spray is Veracue’s spray-dispensed packaging of Glutathione, a tripeptide built from L-glutamate, L-cysteine and glycine. The underlying molecule is identical to the one documented on Veracue’s Glutathione vial listing, assumed in both cases to be the reduced form (GSH, the thiol form) unless a lot’s own documentation states otherwise; only the packaging and dispensing format differ between the two listings.
"Spray" is a packaging and dispensing descriptor, nothing more. It does not establish a route, a concentration, or a formulation, and none of those specifics should be inferred from the product name. Chemical form, concentration, fill volume and storage conditions are reported on each lot’s own documentation and can be requested through the contact page.

These identifiers describe reduced glutathione as a reference structure. They are not a statement about salt or counterion form, physical form, purity, lot results or storage conditions. Those are reported on each lot’s documentation and can be requested through the contact page.
Veracue lists Glutathione in more than one packaging format because research groups source and track material differently depending on how it is packaged. Keeping the formats as separate listings keeps lot records, images and documentation specific to the packaging a researcher actually ordered, rather than mixing records across formats.
Glutathione Spray and Veracue’s Glutathione vial listing describe one molecule: a tripeptide of L-glutamate, L-cysteine and glycine joined by a gamma-glutamyl linkage and a standard peptide bond, with a free thiol (-SH) on the cysteine residue. Packaging format has no bearing on composition, formula or mass, so these values are identical across both listings.
No. The compound reported under this listing is the same reduced glutathione (GSH) reported under the vial listing. What differs between the two listings is how the material is packaged and dispensed, not its chemical identity.
In Veracue’s catalog, "Spray" is a packaging and dispensing term, comparable to "vial" or "powder" on other listings. It tells a researcher how the product is dispensed from its container. It does not specify a concentration, a carrier, a route, or a formulation, and it is not shorthand for any particular method of use. Those details, where applicable, live in lot-specific documentation rather than in the catalog name.
Treating a packaging word as a technical specification is a common source of error when comparing listings across suppliers. A researcher documenting materials in a methods section should cite the lot’s own documentation for format-specific details rather than inferring them from the word "Spray" alone.
GSSG forms when two GSH molecules are joined by a disulfide bond between their cysteine residues during oxidation. The result is a different molecule with roughly twice the mass, a different formula and a different CAS number. A document that says only "glutathione" and gives no CAS number leaves the form open, and this applies to a spray-format lot exactly as it applies to a vial.

This table compares molecular identity only. Catalog format is listed separately because it is a packaging detail, not a property of the molecule itself, and it does not change which redox state a given lot actually contains.
The free thiol on the cysteine residue is the redox-active site of the molecule. Glutathione peroxidases use GSH to reduce hydrogen peroxide and lipid peroxides, becoming GSSG in the process, and glutathione reductase converts GSSG back to two GSH molecules using NADPH. Glutathione S-transferases separately conjugate GSH to electrophilic compounds, a pathway studied in drug-metabolism research. Glutathione, in either packaging format Veracue offers, is studied as a reference compound in these enzyme systems.
Because "Spray" and "vial" describe packaging rather than chemistry, a methods section should still name the molecule precisely by formula or CAS number and state the redox form tested, then separately note the catalog format and lot number actually used. This page provides molecular reference information and general research context only, and Veracue provides no dosing, administration or usage guidance of any kind.
Identity and purity for Glutathione Spray are established the same way as for any Glutathione lot: reverse-phase HPLC for chromatographic purity, and mass spectrometry (typically LC-MS or ESI-MS) to confirm that the observed mass matches the molecule’s theoretical value for the stated redox form. HPLC alone shows that most detected material elutes together; it does not by itself confirm identity, and it cannot tell GSH from GSSG without a mass result or reference standard.
Packaging format has no bearing on which analytical methods apply. A spray-dispensed lot and a vial lot of the same molecule are verified against the same formula and mass references, listed on the Glutathione at a Glance table above.
| Method | Tells a researcher | Does not prove by itself |
|---|---|---|
| RP-HPLC | Chromatographic purity (area %) | Identity, or whether the sample is GSH or GSSG |
| LC-MS or ESI-MS | Mass consistent with GSH (307.32) or GSSG (612.63) | Purity |
| MS/MS fragmentation | Structural confirmation from fragment ions | A standalone purity measurement |
| Electrochemical or UV assay kits | Thiol redox activity in solution | Specificity without chromatography; not designed for raw material purity |
A certificate of analysis describes one lot, never a packaging format or a compound in general. Before relying on any figure, confirm that the lot number on the certificate matches the container and the order record for the spray-format unit received, and confirm which redox form the certificate actually covers.
A complete certificate separates product identity, lot number, redox form and CAS number, HPLC result, mass spectrometry result with observed and theoretical mass, test date and testing laboratory. Where concentration or fill-volume figures are relevant to a spray-format unit, they are reported on that lot’s own documentation rather than inferred from the catalog listing. The certificate page explains how to request lot documentation for either format.
No. The verification question is the same: does this lot match the stated redox form, and is the purity figure paired with a mass result from the same lot. Packaging format does not change what counts as adequate documentation.
GSH and GSSG share a chemical relationship but carry different formulas, masses and CAS numbers. If a lot’s documentation leaves the form unstated, any mass-based calculation can carry a silent error. Confirm the form on the lot’s certificate and use the matching molecular weight, regardless of packaging format.
For each lot, keep the catalog listing snapshot, the lot-specific certificate, the stated redox form, the receipt date, labeled storage conditions, and the packaging format actually received. Recording format alongside the usual identity fields keeps multi-format catalogs like this one traceable lot to lot.
