What is Selank?

Selank is a synthetic heptapeptide analogue of the immunomodulatory tetrapeptide tuftsin. Developed in Russia, it has been studied for anxiolytic (anti-anxiety), nootropic, and immunomodulatory effects. Researchers study Selank for its effects on serotonin, dopamine, and GABA neurotransmitter systems.

Research Dosing Parameters

  • Typical dose range: 250–500 mcg per administration
  • Common vial size: 5 mg
  • Reconstitution: 2 mL bacteriostatic water (for injectable use)
  • Administration routes: Subcutaneous injection or intranasal in research
  • Frequency: 1–2x daily in most research protocols

How to Reconstitute Selank

  1. Use bacteriostatic water for injectable reconstitution
  2. Inject slowly along the vial wall
  3. Swirl gently until dissolved
  4. Store at 2–8°C; use within 30 days
  5. For intranasal use, specialized formulations are typically used

FAQ

What is the difference between Selank and Semax? Both are nootropic peptides, but Selank has more pronounced anxiolytic properties while Semax is more focused on cognitive enhancement and BDNF upregulation. They are sometimes used together in research.

Can Selank be administered intranasally? Yes, intranasal administration is studied as an alternative to subcutaneous injection for Selank. Use the calculator above for subcutaneous dose calculations.
