Overview
Selank is a synthetic peptide derived from the immune-regulating peptide tuftsin, developed in Russia and studied there for anxiety, mood, and cognitive effects.
How It's Thought to Work
Research suggests Selank may influence GABA and serotonin systems and brain-derived neurotrophic factor (BDNF), which are involved in anxiety and cognition.
What the Research Says
Most clinical research is Russian and relatively small; it is used clinically in some countries but has little Western regulatory review.
Regulatory & Legal Status
Not FDA-approved. Sold as a research chemical in most Western markets.
Safety Considerations
Limited Western safety data; unregulated product quality. Consult a qualified clinician.
