Glutathione — research reference, shipped from Colombia

Presentations and visible prices

The price above is the public value per vial. Availability and batch documentation are confirmed before the quotation is accepted.

A named tripeptide within 'other compounds'

The catalog classifies Glutathione as a tripeptide: gamma-glutamyl-cysteinyl-glycine, meaning three amino acids — glutamic acid, cysteine, and glycine — joined in that order through a particular bond at the first of them. That is a precise, verified structural classification, unlike other references in the same commercial category, such as SHB, which has no declared molecular family in the catalog.

The catalog's 'other compounds' category, then, does not mean a reference lacks a structural classification: it commercially groups entries that do not fit the catalog's more specific thematic categories, such as the metabolic axis or immunomodulation, regardless of whether their molecular family is verified. Glutathione is an example of a reference with a declared family within that broad category.

Immediate delivery: what changes versus the rest of the catalog

Unlike most catalog references, which are handled on a made-to-order basis with a 15-day coordination window, Glutathione is listed in the catalog with immediate delivery, the same condition as NAD+. That means, barring changes to declared inventory, dispatch coordination does not depend on an additional manufacturing or import lead time once the quote is confirmed.

That immediate-delivery status does not change the documentary verification procedure: the lot's certificate of analysis is still required to confirm identity and purity, and storage still depends on the documentation applicable to the dispatched lot. Delivery speed is a logistics data point, not a substitute for the documentary control that applies to the rest of the catalog.

1500mg presentation and physical form

Glutathione is offered in a single presentation of 1500 mg, measured by mass, which corresponds to a lyophilized powder in a vial under the criterion the catalog applies. Being the only presentation available for this reference, the institutional request does not need to distinguish between milligram variants: it only needs to confirm the exact name, the code, and the number of vials required, without that being confused with higher concentration or potency.

The current price for this presentation is shown in the commercial block of this page and should be confirmed in writing before authorizing payment. That written confirmation, together with the receipt and the receiving record, is the evidence that allows the purchase to be reconstructed for an internal audit, without relying on comparing the price to another catalog reference.

Janoshik's COA applies to this category too

Glutathione's certificate of analysis is issued by Janoshik Analytical, per lot, using HPLC for purity and mass spectrometry for identity, the same documentary procedure that applies to any other catalog reference, regardless of its commercial category. The fact that Glutathione is grouped under 'other compounds' does not reduce or replace the requirement to verify the lot through this certificate.

This page does not publish a purity percentage, a CAS number, a detailed structural formula beyond the tripeptide's name, or a molecular weight, because those specific analytical figures are not verified in the documentation available for this page. The name gamma-glutamyl-cysteinyl-glycine identifies the class of molecule; the lot's COA is what confirms its specific identity and purity.

Storage conditions declared for this reference

Glutathione's storage conditions are set by the documentation applicable to the lot, the same as for the rest of the catalog. If that documentation specifies a 2-8 °C range and protection from light, the receiving institution should build that condition into its custody record. Immediate-delivery status does not change this requirement: the material must be received and stored per what the specific lot's documentation declares.

As an immediate-delivery reference, dispatch coordination can move faster than for other catalog references handled on a made-to-order basis. Shipping fees to Bogota and to other cities are set out on the site's shipping information page and are confirmed during the institutional quote along with the estimated delivery date. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.

How it differs from SHB within the same category

Glutathione and SHB share the 'other compounds' commercial category, but differ on one central point: Glutathione has a declared, verifiable molecular family — a tripeptide of known composition — while SHB is, per the catalog's documentation, a supplier code with no declared composition. That difference should be clear in any comparison between the two references.

A Glutathione order is recorded first, the quote is confirmed in writing, and payment is coordinated afterward. The recommended purchase file brings together the request, the quote, proof of payment, dispatch confirmation, the receiving record, and Janoshik's certificate for the lot when one was requested, the same as for the rest of this catalog's references.
