Selank

🔬What Is Selank

Selank is a synthetic heptapeptide anxiolytic developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is based on the naturally occurring immunomodulatory peptide tuftsin (threonyl-lysyl-prolyl-arginine) with an added Gly-Pro sequence for enhanced stability. Selank modulates the GABAergic and serotonergic systems, producing anxiolytic effects comparable to benzodiazepines but without sedation, cognitive impairment, or addiction potential. It has been approved in Russia as a prescription medication for generalized anxiety disorder. Research demonstrates its ability to increase BDNF (Brain-Derived Neurotrophic Factor) expression, enhance memory consolidation, and modulate IL-6 cytokine expression for immunomodulatory benefits.

📊Clinical Studies & Results

Selank (TP-7) is a synthetic analogue of the immunomodulatory peptide tuftsin, with extensive research on its anxiolytic and immunoregulatory properties:

• ▪Demonstrated anxiolytic efficacy comparable to benzodiazepines in clinical trials for generalized anxiety disorder, without sedation or cognitive impairment (Zozulya et al., Zh Nevrol Psikhiatr, 2008)
• ▪Modulated expression of 45 genes involved in GABAergic neurotransmission in neuronal cell lines, including GABRA2, GABRA6, and GABRB1 subunits (Kasian et al., Front Pharmacol, 2016; PMID: 26924987)
• ▪Increased IL-6 production and stabilized enkephalin levels in blood, suggesting dual anxiolytic-immunomodulatory mechanism of action
• ▪Enhanced the expression of BDNF mRNA in the hippocampus, contributing to neuroplastic and antidepressant-like effects in animal models
• ▪Inhibited enkephalinase activity, prolonging the half-life of endogenous opioid peptides and contributing to natural stress resilience
• ▪Showed no addictive potential, withdrawal symptoms, or tolerance in any published clinical or preclinical study

Selank represents a unique class of peptide anxiolytics that combines GABAergic modulation with immunoregulatory properties, offering anxiolytic effects without the drawbacks of classical benzodiazepines.

🏆Benefits

• Reduces Anxiety Without Sedation – Clinically comparable to benzodiazepines without drowsiness
• Modulates GABA System Naturally – Upregulates key GABA receptor subunit genes for balanced neurotransmission
• Immunomodulatory Properties – Stabilizes immune markers and enhances adaptive immune response
• Enhances Stress Resilience – Prolongs endogenous enkephalin activity for natural coping
• Supports Neuroplasticity – Increases BDNF expression in memory-critical brain regions
• No Addiction or Withdrawal Risk – Zero dependence potential across all published research

⚠️Possible Side Effects

• ▪Very well tolerated – one of the safest nootropic peptides available
• ▪No documented sedation, cognitive impairment, or motor coordination issues
• ▪Rare mild nasal irritation with intranasal use
