What is Selank?

Selank is a synthetic peptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It combines anxiolytic (anti-anxiety) properties with cognitive enhancement and immunomodulation — a unique combination not found in traditional pharmaceutical approaches.

Research Applications

Anxiety research (without sedation), cognitive enhancement under stress, memory and learning studies, immunomodulation, and BDNF expression research.

Dosage Information (Research Use)

Research protocols: 200-600 mcg/day, subcutaneous or intranasal. Duration typically 14-30 days in published studies. Research use only.

Reconstitution & Handling

Standard BAC water reconstitution for subcutaneous use. Can also be prepared in saline for intranasal research.

Half-Life & Pharmacokinetics

Several minutes in plasma, but functional CNS effects persist for hours, suggesting tissue-level accumulation or downstream signaling cascades.

Reported Observations in Literature

Remarkably clean safety profile in published data: no sedation, no cognitive impairment, no addiction or tolerance, no withdrawal. Mild nasal irritation with intranasal route.

How Selank Works

Selank is a synthetic heptapeptide analog of the immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro sequence for enzymatic stability. It modulates GABA-ergic, serotonergic, and dopaminergic systems. Research shows influence on brain-derived neurotrophic factor (BDNF) expression, enkephalin metabolism, and IL-6 modulation. Acts as an anxiolytic without sedation or cognitive impairment — a distinction from benzodiazepine-class compounds.

Research Findings

Approved as a nasal spray anxiolytic in Russia. Research demonstrates cognitive enhancement under stress conditions, memory consolidation improvement, and immune system modulation. Notably lacks addiction potential, tolerance development, or withdrawal effects in published studies.

Dosage & Administration

Research protocols: 200-600 mcg/day, subcutaneous or intranasal. Duration typically 14-30 days in published studies. Research use only.

Safety & Side Effects

Remarkably clean safety profile in published data: no sedation, no cognitive impairment, no addiction or tolerance, no withdrawal. Mild nasal irritation with intranasal route.

Important: All safety information is derived from published research, primarily animal studies. No controlled human clinical trial data exists unless explicitly noted. This compound is sold for research purposes only.
