Selank is studied for GABA-A modulation, BDNF expression, and neuroimmune regulation without sedation or dependence. In stock and ships same day on orders placed before 2 PM EST.

What Is Selank?

Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin, extended with a Pro-Gly-Pro tail that stabilizes the molecule and prolongs its activity. Developed at the Institute of Molecular Genetics in Moscow, it is one of the most thoroughly documented anxiolytic peptides outside the benzodiazepine class. Our Selank research guide covers the full background.

Laboratories buy Selank to study an unusual profile: benzodiazepine-like anxiolysis in preclinical models with no sedation, no tolerance, no cognitive impairment, and no withdrawal after chronic dosing. It crosses the blood-brain barrier efficiently and tolerates intranasal, subcutaneous, and intraperitoneal delivery, which makes it a practical tool peptide for stress-response, learning, and neuroimmune research.

Key Research Applications

• Anxiolytic research: Non-sedating GABA-A modulation across elevated plus maze, open field, Vogel conflict, and social defeat paradigms.
• Nootropic studies: BDNF-mediated neuroplasticity, memory consolidation, attention, and cognitive resilience under stress.
• Neuroimmune axis: Cytokine modulation and tuftsin-derived immunomodulation in neuroinflammatory models.
• Combination research: Selank + Semax co-administration for anxiolytic-nootropic endpoints.
• Monoamine interaction: Serotonin metabolism and dopamine turnover in cortical and limbic regions.
• Chronic administration safety: Long-duration dosing without tolerance or withdrawal markers.
