What it does
Selank is a synthetic heptapeptide developed at the Russian Academy of Medical Sciences as a stable analog of the endogenous immunomodulator tuftsin. It is one of the most extensively studied nootropic / anxiolytic peptides in Russian neuropharmacology, with research demonstrating fast-acting anti-anxiety effects without sedation, dependence or withdrawal — a profile distinct from benzodiazepines.
How it works in the body
It gently turns down the brain's 'alarm' chemistry and turns up the calm, focused chemistry — without sedating you or making you foggy. It also calms down inflammation signals that can make stress feel worse. Sprayed in the nose, it reaches the brain in minutes.
Researched benefits
- Reduced anxiety and stress reactivity without sedation
- Improved focus, mental clarity and verbal recall
- Stabilised mood and resilience during high-stress periods
- Immunomodulatory support — gentler cytokine profile
- No tolerance, dependence or rebound anxiety on withdrawal
Typical research protocol
- Reconstitution
- Add 2 mL bacteriostatic water to the 10 mg vial → 5 mg/mL (1 pen unit = 0.05 mg / 50 mcg).
- Dose
- Typical research dose: 0.25–0.5 mg (250–500 mcg) per administration.
- Pen units (U-100)
- At 5 mg/mL: 0.25 mg (250 mcg) = 5 units, 0.5 mg (500 mcg) = 10 units on a U-100 peptide pen.
- Frequency
- 1–3× per day, typically used in 10–14 day cycles.
Recommended: use a single-use, sterile drawing syringe and needle for reconstitution — available in the accessories section.
For in-vitro research only — not for human or veterinary consumption.
Potential side effects
- Nasal irritation or a bitter drip with intranasal use
- Mild drowsiness or flat affect at higher doses
- Transient headache
- Rare fatigue on the day after use
