About Selank

Selank is a synthetic heptapeptide developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. It was derived from tuftsin, a tetrapeptide with immunomodulatory properties, with a stabilizing extension. Selank has anxiolytic (anxiety-reducing) properties and is classified as a nootropic peptide.

Unlike conventional benzodiazepine anxiolytics, Selank does not appear to cause sedation, tolerance, or withdrawal. Its mechanism is thought to involve modulation of the GABAergic system and stabilization of enkephalins (endogenous opioid peptides). Research has also explored its effects on serotonin, dopamine, and BDNF (brain-derived neurotrophic factor) levels.

Selank is approved in Russia as an anxiolytic medication. In research contexts outside Russia, it is studied for anxiety reduction, cognitive enhancement, mood stabilization, and immune modulation. It is typically administered via subcutaneous injection or intranasal route.

Selank is supplied in 10mg vials. Using 2ml of bacteriostatic water gives 5,000 mcg/ml. Common research doses range from 250–750mcg, administered 1–2 times daily. It has a relatively short half-life of 1–2 hours.

Frequently Asked Questions

Common research doses range from 250–750mcg per injection, 1–2 times daily. For a 10mg vial + 2ml BAC water (5000 mcg/ml), 250mcg = 0.05ml = 5 units.
Selank modulates the GABAergic system (similar to anxiolytics), stabilizes enkephalins, and may influence serotonin and dopamine. Unlike benzodiazepines, it reportedly lacks sedative, addictive, or withdrawal properties.
Selank is primarily anxiolytic (anti-anxiety) and mildly cognitive-enhancing. Semax is more stimulating and cognitive-enhancing with less anxiolytic character. Some researchers combine both for balanced nootropic effects.
Yes — Selank was originally developed as a nasal spray and can be administered intranasally. For intranasal use, a higher concentration is typically prepared. Injectable Selank gives more precise dosing.
Add 2ml of bacteriostatic water to a 10mg Selank vial for 5000 mcg/ml. Inject slowly along the glass wall. Gently swirl until dissolved. Refrigerate at 2–8°C. Stable approximately 28–30 days.
