Selank

Selank is a synthetic peptide developed in Russia that combines anti-anxiety effects with cognitive enhancement — without the sedation or addiction risk of traditional anti-anxiety medications. **What makes it unique?** Selank is based on tuftsin, a natural immune-regulating peptide in your body, with an added sequence to make it more stable. This gives it a dual action: it calms anxiety while sharpening mental function. **What the research shows:** • Reduces anxiety without causing drowsiness or impairment • Increases BDNF (brain-derived neurotrophic factor) — a protein crucial for learning and memory • May help with focus, memory consolidation, and mental clarity • Shows immune-modulating properties • Can reduce symptoms of alcohol withdrawal **How it works:** Selank influences multiple neurotransmitter systems including serotonin and dopamine, but in a balancing way rather than overwhelming them like some pharmaceuticals. **Typical use:** Usually administered as a nasal spray for direct brain delivery, though injectable forms exist. **Important to know:** Selank is approved in Russia for anxiety and cognitive disorders but is not FDA-approved in the United States. Research is promising but primarily from Russian institutions. --- **Sources:** Seredenin SB, et al. (2019) Bulletin of Experimental Biology and Medicine.
