What it is
Selank is a synthetic heptapeptide analogue of the immunomodulatory peptide tuftsin, developed in Russia as an anxiolytic with nootropic properties. It is frequently studied alongside Semax.
Mechanism
Selank modulates GABAergic transmission (allosteric effect on GABA-A receptors), influences serotonin and enkephalin metabolism by inhibiting enkephalin-degrading enzymes, and increases BDNF expression. It also has documented effects on cytokine balance.
Research areas
- Anxiety and stress models
- Cognitive function and learning
- Immunomodulation
- Enkephalin and GABA systems
- Sleep and mood
Safety and metabolism
Clinical use in Russia with a benign safety profile; no sedation or dependence reported. Short half-life; rapidly metabolised.
Why this amount
10 mg is the standard research vial and the basis for the upcoming nasal-spray format.
