Selank Pen Refill Kit

Selank — The Calm Peptide

• Supports calm without sedation
• Influences GABA signalling
• Supports focus under stress

Overview

This product is supplied as a kit, not as a pre-filled cartridge. Everything needed to prepare a pen cartridge 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.

A reconstituted cartridge is a liquid preparation with a limited stable life, and transit conditions cannot be controlled. Supplying the compound 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 10mg.

What's in the kit

• 1 × Selank vial — lyophilised powder, 10mg
• 1 × bacteriostatic water, 3ml — for reconstitution
• 1 × pen cartridge — empty, ready to fill
• 1 × insulin needle

The cartridge fits our peptide pens. Our reconstitution calculator will work out the concentration and draw volume for the water volume you use.

Research Focus

Selank is a synthetic heptapeptide analogue of tuftsin, developed in Russia and also known as TP-7. It is studied chiefly as an anxiolytic, and what distinguishes it in the literature is that research reports anxiolytic activity without the sedation, cognitive dulling or dependence associated with benzodiazepines. Published work has examined its influence on GABAergic signalling, expression of BDNF, inhibition of enkephalin degradation, and attention and memory under stress conditions.

Research on Selank includes both human clinical studies, largely published in Russian-language journals, 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.
