Overview

Selank is a synthetic analogue of the immunomodulatory peptide tuftsin, developed alongside Semax at the same Russian institute.

Reported anxiolytic effects without sedation or dependence are the main interest. The supporting evidence is thin by international standards.

Why It's Being Studied

  • Generalised anxiety and adjustment disorders.
  • Interaction between immune signalling and mood.
  • GABAergic and serotonergic modulation.

Mechanism of Action

In plain language

It appears to calm anxiety-related signalling in the brain, apparently through immune and neurotransmitter pathways rather than sedation.

Technical detail

Selank is reported to modulate GABA-ergic transmission, alter serotonin metabolism and influence enkephalin degradation by inhibiting enkephalin-degrading enzymes. Immunomodulatory effects on interleukin expression have also been described in rodent and human cell work.

Research Areas & Routes Studied

Areas studied
  • Anxiety
  • Cognition
  • Immune signalling
Routes used in research
  • Intranasal

Evidence Summary

Small Russian studies in anxiety disorders with limited methodological transparency; no independent international trials.

Human clinical evidence

  • Small Russian trials in anxiety disorders report effects comparable to benzodiazepine comparators.

Animal studies

  • Rodent anxiety models and neurotransmitter studies.

Anecdotal / community information

  • Nootropic community reports of reduced anxiety; uncontrolled.

Reported Adverse Events in Research

  • Nasal irritation reported; no systematic international safety data.

Limitations of Current Evidence

  • Very limited, regionally concentrated evidence.
  • No established international dosing protocol.

Why It Is Used

  • Cognitive

    Focus, Mood and Cognitive Load

    Two Russian-developed peptides used together for the same reason people pair a stimulant with an anxiolytic: attention without the edge.
