Selank (CAS: 129954-34-3) is a synthetic tetrapeptide, a bioengineered analog of the natural immunomodulatory peptide tuftsin, originally developed in Russia for its unique anxiolytic and neurotrophic effects. Unlike traditional anxiety-relieving agents, Selank exerts its effects without sedation or cognitive impairment, making it a sought-after nootropic for balancing calm and focus, with additional neuroprotective and immune-supporting benefits. Its small molecular structure enables efficient blood-brain barrier penetration, ensuring direct and fast action on central nervous system cells.
