SELANK

Selank is a synthetic peptide, derived from the natural immune peptide Tuftsin, developed in Russia as a potent anxiolytic (anxiety-reducing) and nootropic (cognitive-enhancing) agent, used clinically to promote calmness, mental clarity, and focus by modulating neurotransmitters like serotonin and dopamine, potentially supporting mood, memory, and immune function with fewer sedative side effects than traditional drugs, though its use remains largely outside mainstream FDA approval.
