Selank peptide (10 mg vial)

What is Selank?

Selank is a synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, built from tuftsin (a natural fragment of immunoglobulin G) with the same stabilising Pro-Gly-Pro tail used in Semax. It was developed at the Institute of Molecular Genetics in Moscow and registered for clinical use in Russia in 2009. Supplied here as lyophilised powder at 99%+ HPLC purity in a 10 mg sealed vial for laboratory research.

This Selank 10mg vial is the raw Selank peptide; the Selank vial ships from UK stock.

What the research covers

Russian clinical studies in anxiety disorders report anxiolytic effects comparable to low-dose benzodiazepines without sedation, tolerance or withdrawal; mechanistic work points to modulation of GABAergic transmission and effects on serotonin and enkephalin metabolism. There are no Western controlled trials, and it is not licensed as a medicine outside Russia.

Selank and Semax

The two peptides come from the same institute and share the Pro-Gly-Pro tail but have different parent fragments and different research targets: Semax for attention and learning, Selank for stress and anxiolytic activity. Both are stocked here; see Semax. A finished Selank nasal spray is in development at our sister brand COGENT.

Quality and testing

Each lot of Selank is sent to an independent UK laboratory before release for identity by mass spectrometry, purity by HPLC, residual solvents and bacterial endotoxin. The lot number on the vial label matches the certificate on our certificates page, and no lot is released for sale until the certificate is in hand. Specification: ≥ 99% (HPLC), supplied as lyophilised powder, 2 ml glass vial, sealed, 10 mg per vial.

Reconstitution and handling

Selank arrives as a lyophilised cake under an aluminium crimp seal. Let the vial reach room temperature before opening so that condensation does not form on the powder. Swab the stopper with an alcohol swab, draw the chosen volume of bacteriostatic water with a sterile syringe, and add it slowly down the inside wall of the vial rather than onto the powder. Swirl gently until clear; never shake, which can denature the peptide. Label the vial with the date and concentration. The peptide calculator converts vial amount and diluent volume into concentration, millilitres and U-100 syringe units for any target amount. Sealed vial: -20 °C, protected from light. Reconstituted: 2 to 8 °C, use within 4 weeks.

Lot traceability

Every Selank vial carries a printed lot number and expiry. The same lot number appears on the certificate of analysis for that batch, which names the testing laboratory and the report number so it can be verified directly. If the number on your vial does not match a certificate on our site, contact support before using it. Certificates are kept online for the life of the product plus two years.

Handling and storage

Sealed vial: -20 °C, protected from light. Reconstituted: 2 to 8 °C, use within 4 weeks. Keep sealed until use. Allow the vial to reach room temperature before opening to avoid condensation on the powder. Reconstitute with bacteriostatic water added slowly down the wall of the vial; do not shake.
