Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro).
Developed in Russia by the Institute of Molecular Genetics as an anxiolytic (anti-anxiety) peptide.
Derived from tuftsin, a natural immunomodulatory peptide.
Sometimes described as a “nootropic peptide” because it influences mood, cognition, and immune function.
Neurotransmitter modulation: Increases brain levels of serotonin and dopamine metabolism.
BDNF upregulation: Stimulates Brain-Derived Neurotrophic Factor, supporting learning and memory.
Anxiolytic action: Enhances GABAergic signaling → calming effect without sedation or dependence (unlike benzodiazepines).
Immune effects: Modulates cytokine balance (supports antiviral and anti-inflammatory activity).
Anxiety reduction (similar effect to mild anxiolytics, but non-sedating).
Improved focus & memory (via BDNF and neurotransmitter support).
Antidepressant-like effect (through serotonin and dopamine pathways).
Stress resilience (blunts overactive stress response).
Immune support (may enhance antiviral defenses).
Investigated for: GAD (generalized anxiety disorder), depression, ADHD, and PTSD.
Considered very safe in available human studies.
No reports of addiction, withdrawal, or major toxicity.
Mild, rare side effects: nasal irritation (spray), headache, or fatigue.
Non-sedating, so can be taken during daytime without impairing function.
Selank = anxiolytic, nootropic peptide derived from tuftsin.
Benefits: reduces anxiety, improves focus and memory, supports mood and immune balance.
Dosing: typically 250–500 mcg intranasal, 2–3× daily, for 10–30 days.
Status: Approved in Russia; experimental elsewhere.
Advantage: calming effect without sedation or dependence (unlike benzos).
