Description
GSH Glutathione is a research-grade reagent for laboratories and qualified buyers sourcing research peptides in Canada. Glutathione is the reduced (thiol) form of the tripeptide γ-glutamyl-cysteinyl-glycine, one of the most studied small molecules in redox biology, and it is supplied here as a lyophilized powder in a sealed vial for reconstitution in a solvent appropriate to your protocol. It is intended for in-vitro and laboratory research only, not for ingestion or administration to humans or animals.
Overview
Each vial contains lyophilized GSH in either a 600 mg or 1500 mg fill, available singly or in a box of ten for labs running repeat work or multiple arms of a study. The dry powder format is deliberate: reduced glutathione carries a free thiol group that oxidizes readily in solution to the disulfide GSSG, so keeping the material dry until the point of use gives the researcher control over when the clock starts. Reconstitution volume and solvent are left to the investigator, which allows the same vial to be worked up to whatever stock concentration the assay calls for. Every batch is analyzed by Janoshik, an independent third-party analytical laboratory, for purity by HPLC and identity by mass spectrometry, and the certificate of analysis matched to your batch is available on request. Orders are stored cold, packed discreetly and shipped from within Canada with tracking.
What it is known for
Buyers know this product for two things: documentation and format. The batch-matched third-party COA — HPLC purity plus MS identity from an outside lab rather than an in-house claim — means the material can be logged with real analytical backing instead of a supplier’s word. And because glutathione is one of the reagents most vulnerable to handling error, the lyophilized presentation in a defined fill weight is what makes it practical to use reproducibly. Sourcing domestically also removes the customs delays and temperature exposure that come with cross-border shipments of an oxidation-sensitive compound.
Key features
- Reduced (GSH) form of the tripeptide — The thiol form is the one relevant to redox and thiol-chemistry work, so the material is fit for purpose without conversion or pre-treatment.
- Lyophilized powder presentation — The dry state limits oxidation to GSSG before use, so the reagent is stable in storage and the researcher decides when it goes into solution.
- HPLC purity testing by an independent lab — Chromatographic purity from a third party tells you what fraction of the vial is the compound you ordered — the figure that governs whether your concentrations are real.
- Mass spectrometry identity confirmation — Confirms the molecular identity of the material rather than assuming it, which is the difference between a labelled vial and a verified one.
- Batch-matched certificate of analysis — The paperwork corresponds to the specific lot in your hand, so results can be traced back to a documented batch when you write them up.
- Two fill weights, single vials or boxes of ten — Lets you buy a single vial for method development and scale to a case for a full run without switching supplier or batch mid-study.
- Cold storage and discreet, tracked Canadian shipping — Domestic dispatch keeps transit short for a temperature- and oxidation-sensitive reagent, and tracking gives you a delivery date you can plan bench time around.
Benefits
- You can verify what you received before it enters an experiment, instead of relying on a label.

Important information
- Research use only. This product is not a drug, supplement, food or cosmetic, is not intended to diagnose, treat, cure or prevent any disease, and is not for human or veterinary use, ingestion or administration.
- Keep vials cold and sealed until use, and protect the powder from moisture and air.
- Reduced glutathione oxidizes to GSSG in solution — prepare working solutions close to the time of use and store reconstituted material according to your own validated protocol.
- Choose a reconstitution solvent appropriate to your assay and confirm compatibility with downstream detection methods before committing a full vial.
- Request the certificate of analysis for your batch and file it with your experimental records.
- Confirm the fill weight you need before ordering; 600 mg and 1500 mg vials are supplied singly or in boxes of ten.
Common questions
Is this reduced glutathione or the oxidized form?
It is GSH, the reduced form of the tripeptide, supplied as a lyophilized powder. Reduced glutathione converts to the disulfide GSSG on exposure to air and in solution, which is why it ships dry.
What testing has been done, and can I see it?
Each batch is tested by Janoshik, an independent analytical laboratory, for purity by HPLC and identity by mass spectrometry. A certificate of analysis matched to your batch is available.
How should I reconstitute it?
Reconstitution is left to the researcher, since the appropriate solvent and final concentration depend entirely on the assay. Choose a solvent compatible with your protocol and calculate volume from the fill weight of the vial.
What is the difference between the single vial and the box of ten?
Only quantity. A single vial suits method development or a short run; the box of ten is for repeat work or multi-arm studies where you want consistent material across experiments.
How is it stored and shipped?
It is held in cold storage and shipped discreetly from within Canada with nationwide tracking. Keep vials cold and sealed on arrival.
Can this be used by or on people or animals?
No. It is sold strictly for laboratory research and is not a drug, supplement, food or cosmetic. It is not intended for human or veterinary use, ingestion or administration.
In summary
A lyophilized GSH reagent with independent HPLC purity and MS identity data behind every batch, offered in 600 mg and 1500 mg vials singly or by the ten, and shipped cold and tracked from within Canada. If your work depends on knowing exactly what is in the vial before it reaches the bench, that documentation is the reason to choose it.
