Research overview

About Selank

Selank is a synthetic heptapeptide analog of the naturally occurring immunomodulatory peptide tuftsin.

It is primarily researched for its unique anxiolytic (anti-anxiety) and nootropic properties. Unlike traditional anxiolytics, Selank is studied for its ability to reduce anxiety and stress while enhancing cognitive function, memory, learning, and focus — all without causing sedation or withdrawal effects. It is also investigated for its neuroprotective and immune-modulating benefits.

Key Research Areas

  • Anxiety, stress, and emotional regulation models
  • Cognitive enhancement, memory, and learning
  • Neuroprotection and brain health
  • Immune system modulation
  • Mood stabilization and mental performance studies
