Selank-13mg

Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derived from the natural immunomodulatory peptide tuftsin. It is studied for its role in anxiety regulation, memory, and stress resilience, with additional interest in immune modulation.

Benefits

• Anxiety regulation — studied as a potential anxiolytic in clinical and preclinical research.
• Memory and learning — linked to enhanced recall and cognitive performance in models.
• Stress resilience — explored for maintaining balance under chronic stress conditions.
• Immune system balance — reported shifts in cytokine profiles toward a healthier immune response.
• Synergy with GABA pathways — transcriptomic data suggest modulation of GABA-related genes.

What researchers look at

• Impact on hippocampal BDNF expression and neurotrophin levels.
• Modulation of GABA-related genes and signaling pathways.
• Clinical comparisons to benzodiazepines in anxiety spectrum disorders.
• Immune modulation effects, shifting Th1/Th2 cytokine balance.
