About Selank

A synthetic heptapeptide analogue of tuftsin studied for anxiolytic effects, cognitive enhancement, and immunomodulation without sedation.

Research dose ranges

  • Dose: 250–3000 mcg per administration
  • Frequency: 2× per day
  • Route: nasal
  • Half-life: ~0.033 hours
  • Cycle: 4 weeks on / 2 off

Selank is most commonly used as an intranasal solution (0.15% concentration). Research protocols vary from 250 mcg to 3 mg per day divided into 2–3 intranasal administrations. Clinical studies in Russia used 250–900 mcg daily for anxiety disorders.

Storage

Refrigerate at 2–8°C. Protect from light. The prepared intranasal solution remains stable for approximately 30 days under refrigeration.

Selank calculator FAQ

How do I use the Selank calculator?+

Confirm your vial size in mg (default 0.25), set the diluent volume in mL (default 1), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard Selank reconstitution?+

Most Selank research protocols reconstitute a 0.25 mg vial with 1 mL of bacteriostatic water, yielding 250 mcg/mL.

What syringe should I use for Selank?+

U-100 insulin syringes are standard for Selank nasal administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the Selank calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
