Glutathione 1500 mg for UAE laboratories

The catalogue line is L-glutathione in the reduced form — the γ-Glu-Cys-Gly tripeptide, CAS 70-18-8, 307.32 g/mol — supplied sealed and lyophilised at a nominal 1500 mg. There is one strength and one presentation; no solution, no smaller fill, and no diluent in the box. Diluents are ordered separately from research support.

At gram scale the unit functions as laboratory stock. Plan the first open as a documented step: equilibrate the sealed container to ambient temperature so moisture does not condense on the powder, weigh promptly, aliquot into campaign portions, and record the first-open date against the lot. A parent container reopened weekly for a quarter has a history no certificate describes.

Reduced glutathione and its oxidised disulfide form are different analytical entities, and the free thiol in the reduced form is what makes the material sensitive to air and moisture. A method written against the reduced form is not satisfied by material that has partly oxidised in a badly handled container, which is why the appearance note and the storage condition on the label are worth reading rather than skimming.

In practice: keep the container sealed and cold between uses, minimise headspace exposure, prepare working solutions close to the point of use, and record preparation dates. If your assay is sensitive to the redox state, write a confirmatory check into your own acceptance criteria rather than inferring it from a purity figure on the certificate.

Per-lot certificates are published to batch verification once uploaded, and the glutathione COA index reaches the same records from the product page. Match compound name, strength and lot before the unit is released, and note whether the record describes independent or supplier-generated analysis. The COA interpretation guide covers the fields that matter.

Because one lot may support a long run of work, the receiving record should be fuller than usual: lot, condition on arrival, date and time of receipt, and the person who accepted it. If a lot is not yet published, submit a documentation request with the lot and order reference and hold the unit in quarantine.

Sealed material is kept cold, dry and protected from light per the printed label and lot record; dispatch covers the seven emirates and checkout is in AED. Move the parcel out of ambient conditions before the paperwork is finished, which in Gulf summer months matters more than anything the courier does. Site policy guidance is in the research peptide storage guide.

This material is a research reagent. VaultLabs makes no claims about appearance, physiology, pigmentation or wellbeing, supplies nothing for human or animal use, personal use, cosmetic use or medical application, and provides no administration or preparation guidance for living systems. Catalogue context for comparative analytical work sits on the glutathione and NAD+ comparison.
