Glutathione Pen Refill Kit

Glutathione — The Master Antioxidant

• Supports antioxidant defence
• Supports detoxification
• Supports skin brightness

Overview

This product is supplied as a kit, not as pre-filled cartridges. Everything needed to prepare three pen cartridges is included — the powder is shipped sealed and lyophilised, and is reconstituted by you at the point of use rather than by us before dispatch.

Glutathione is markedly less stable in solution than as a lyophilised powder, and transit conditions cannot be controlled. Supplying it dry removes that variable entirely: the material arrives in the state it was tested in, and the clock only starts when you mix it. Available in 1500mg.

What's in the kit

• 1 × Glutathione vial — lyophilised powder, 1500mg
• 1 × bacteriostatic water, 10ml bottle — for reconstitution
• 3 × pen cartridges — empty, ready to fill
• 1 × insulin needle

The cartridges fit our peptide pens. Our reconstitution calculator will work out the concentration for the water volume you use.

Key Specifications

• Product format: Unmixed kit — powder vial, 10ml diluent, three cartridges and needle
• Available sizes: 1500mg total
• Source compound: Glutathione — also available as a lyophilised powder vial
• Purity: Verified by HPLC on every batch — the measured figure for your lot is published on its certificate of analysis
• Preparation: Supplied dry; reconstituted by you at the point of use
• Storage: Store the sealed vial cool, dry and away from light. Glutathione is markedly less stable once in solution, so reconstitute only when you are ready to use it and refrigerate the filled cartridges
• Dispatch: Within 48 hours — each kit is assembled to order
• Intended use: Laboratory research use only

Why three cartridges

A standard pen cartridge holds 3ml. Packing 1500mg into that volume would mean 500mg/ml, which is beyond what glutathione will reliably hold in solution — so the kit gives you three cartridges and a 10ml bottle of water, enough to spread the full amount across all three at a concentration that stays dissolved. The total is the same 1500mg; it is simply prepared in three parts rather than one.

Research Focus

Glutathione is a tripeptide of glutamate, cysteine and glycine, and the body's principal intracellular antioxidant. Published research has examined its scavenging of free radicals and role in oxidative stress; phase II detoxification, where it conjugates to toxins to make them water-soluble for excretion; maintenance of cellular redox balance; and skin pigmentation, where studies have examined its effect on melanin synthesis.

Research on glutathione includes both human studies and animal models.

Testing & Certificates of Analysis

Kits contain the same independently tested powder as our standalone vials — HPLC purity and mass-spectrometry identity, certified per batch and published on our lab results page.

Returns

Kits are assembled to order. An unopened kit with all seals intact can be returned within 14 days — but once the vial, water or needle seal has been broken it cannot be accepted back on hygiene grounds, and anything already reconstituted cannot be returned. Faulty, damaged or incorrect items are always put right. See our refund policy.
