Selank  10 mg | Research Compound

Selank is a synthetic heptapeptide analogue of the naturally occurring tetrapeptide tuftsin, modified to include a glyproline sequence for increased stability. It is primarily studied for its anxiolytic (anti-anxiety) properties and its ability to modulate the metabolism of serotonin and other neurotransmitters in the brain. Unlike traditional sedatives, Selank is investigated for its potential to provide regulatory effects on the central nervous system without inducing drowsiness or cognitive impairment.

Findings from early-stage clinical trials have reported:

  • Reductions in anxiety-related behaviors and stress markers observed in experimental subjects
  • Increased expression of Brain-Derived Neurotrophic Factor (BDNF) reported in hippocampal research
  • Modulation of the GABAergic system and alterations in serotonin metabolism noted in-vivo
  • Enhanced immune system signaling, specifically relating to cytokine balance, observed in research cohorts

Researchers study Selank to investigate the intersection of the nervous and immune systems. Its ability to act as a regulatory agent makes it a valuable tool for exploring neuroprotection, cognitive enhancement, and the biological response to chronic stress. It is a focal point for research into the management of neurochemical imbalances and the preservation of cognitive function during environmental stressors.

Available Formats:
