An anxiolytic peptide that modulates GABA, serotonin, and dopamine signaling — reducing anxiety and stress without the sedation, cognitive dulling, or dependency risk of benzodiazepines.
Selank is a synthetic analog of the immunomodulatory peptide tuftsin, developed at the Institute of Molecular Genetics in Russia. It modulates the balance of inhibitory (GABA) and excitatory neurotransmitter systems, enhances BDNF expression (supporting neuroplasticity), and influences serotonin metabolism. Approved as a nasal spray in Russia for anxiety and cognitive support.
Anxiety disorders are 2x more prevalent in women than men — and perimenopause amplifies this because declining estrogen directly disrupts serotonin, GABA, and dopamine signaling. Selank addresses these exact neurotransmitter pathways without the side effect profile of SSRIs or benzodiazepines. The nasal administration route also appeals to women who prefer non-injectable options.
Selank is well-tolerated in clinical use. Side effects are rare and mild, potentially including nasal irritation (with intranasal administration) and mild fatigue. No dependency, withdrawal, or cognitive impairment has been reported — a key advantage over conventional anxiolytics.

No — Selank does not produce dependency, tolerance, or withdrawal effects. This is one of its primary advantages over conventional anxiolytics like benzodiazepines. It modulates neurotransmitter balance without overriding natural brain chemistry.
Yes — Selank is approved as a nasal spray in Russia and is commonly used in this form. Nasal administration bypasses the GI tract and provides rapid onset. This is appealing for women who prefer non-injectable options.
Selank does not typically cause sedation or cognitive dulling, which distinguishes it from many conventional anti-anxiety medications. Some users report mild relaxation without drowsiness.
