Buy Glutathione Ireland

This page covers glutathione, listed here as L-glutathione or GSH, and sets out the two pack options available to buy in Ireland, the chemistry behind the molecule, and what a shipment to an Irish address involves. Search terms that bring readers here — buy glutathione Ireland, glutathione supplement, l glutathione — usually assume a product taken by a person. What is listed on lumopeptides.com is different: a research-grade substance for laboratory use, priced in euros, with no dosing or usage guidance attached, because none of it is intended for a person or an animal.

Glutathione price and packaging in Ireland

Two packs of glutathione are listed on the site. Both hold 1500 mg of material, in two different formats: a lyophilised vial for reconstitution, and a nasal spray kit that pairs the same lyophilised material with a spray bottle.

Produkt	Pack	Price	Price per unit
Glutathione vial	1500 mg	€ 84,95	€ 0,06 per mg
Glutathione nasal spray kit	1500 mg	€ 94,95	not applicable

The vial is the cheaper of the two and the only one with a stated per-milligram figure, at € 0,06 per mg. The nasal spray kit costs more per pack because the price also covers the spray hardware, so no comparable per-milligram sum is given for it.

What the substance is

Glutathione (GSH) is a tripeptide built from three amino acid residues: L-glutamate, L-cysteine and glycine, written γ-L-glutamyl-L-cysteinylglycine. Unlike most peptide bonds, the link between glutamate and cysteine runs through glutamate’s side-chain carboxyl group rather than its main-chain carbonyl, which is why chemists place a gamma (γ) before its name. The molecular formula is C₁₀H₁₇N₃O₆S, with a molecular mass of 307.32 g/mol and CAS number 70-18-8.

The form listed here is the reduced, thiol-bearing form usually abbreviated GSH and referred to as L-glutathione, distinct from its oxidised dimer GSSG, in which two glutathione molecules are joined by a disulfide bond. Both forms fall into the same class of low molecular weight, sulfur-containing tripeptides used across redox and longevity-related research.

Place in the range

Glutathione sits within the wider peptides range alongside other short chains catalogued for longevity research, among them NAD, a coenzyme rather than a peptide but grouped with glutathione under the same research heading, and GHK-Cu, a copper-binding tripeptide sold in a comparable lyophilised-vial format. None of these substances are interchangeable; each has its own structure, mass and handling notes, and the grouping reflects catalogue category rather than any claim about one substance versus another.

Form, handling and storage

The vial holds a lyophilised, freeze-dried cake. Bacteriostatic water is added slowly down the inside wall of the vial rather than poured directly onto the cake, and the vial is then swirled, not shaken, until the cake has fully dissolved. Once reconstituted, the vial belongs in the fridge, never the freezer.

The nasal spray kit follows the same reconstitution step: the lyophilised material inside it is dissolved with bacteriostatic water in the same wall-pour, swirl-to-dissolve manner, after which the solution is transferred into the kit’s spray bottle. Unopened, sealed material in either format keeps best cool, dry and away from light.

Shipping and analysis

Orders ship from the Netherlands. Delivery to an Irish address is a flat € 14,95, and delivery becomes free once an order reaches € 200. Ireland and the Netherlands are both member states of the European Union, so a parcel moving between the two is an intra-EU shipment rather than an import: it crosses no customs border, and no import duty or VAT is collected from the recipient on arrival.

Every production batch is analysed, and the certificate of analysis for it is kept on file in the lab results archive.

Frequently asked questions

What may I use this for?
Exclusively for laboratory and research purposes, not for human or veterinary use, and with no dosing advice supplied, either on this page or on the product pages themselves.

What is the difference between the vial and the nasal spray kit?
Both hold 1500 mg of the same lyophilised glutathione. The vial is reconstituted and handled as a solution on its own; the nasal spray kit includes a spray bottle that the reconstituted solution is transferred into, which is reflected in its higher pack price.

Is this L-glutathione or the oxidised form?
The material listed here is the reduced form, GSH, commonly written as L-glutathione. The oxidised dimer, GSSG, is a separate substance and is not what is sold on this page.

Do you deliver to Ireland?
Yes, from the Netherlands, at the flat rate given above, with free delivery above € 200. Ireland’s EU membership means no customs charge applies to the parcel.

Can I see the analysis for a batch?
Yes. Each production batch is analysed, and its certificate of analysis is kept on file so the paperwork can be matched to the vial received.
