Selank
Calming nootropic peptide built from the immune peptide tuftsin.
Overview
A synthetic analog of tuftsin approved in Russia as an anxiolytic. Users report calm focus without sedation. Small clinical trials suggest anxiety benefits comparable to mild anxiolytics.
How it works
Modulates GABA signaling, enkephalin breakdown, and serotonin/BDNF expression; also influences cytokine balance.
Evidence
3/5
Small Russian clinical trials in generalized anxiety; limited Western data.
Half-life
Short; effects last hours
Known as
TP-7 analog, Tuftsin analog

The vial outlasts its ~21-day shelf life once mixed. A smaller vial wastes less.
Math only: concentration (mg/mL) = vial mg ÷ mL of water; units = dose (mg) ÷ concentration × 100. Always double-check against your own vial label and a clinician. This tool does not recommend a dose.
Reconstitution
Diluent: Bacteriostatic water (0.9% benzyl alcohol) — allows multiple draws from one vial.
- Wipe both vial tops with an alcohol swab and let dry.
- Draw the diluent, then inject it slowly down the inside wall of the vial — never straight onto the powder.
- Swirl gently or let it sit; do not shake. Foam can damage peptides.
- Solution should be clear. Cloudy, stringy or discolored = discard.
- Common mix: 5 mg + 2 mL = 2.5 mg/mL (300 mcg ≈ 12 units).
Storage
Powder
Freezer / fridge
Keep sealed vial in the freezer (−20 °C) for long-term storage; fridge (2–8 °C) is fine for a few weeks. Keep dry and out of light.
After mixing
~21 days
Refrigerate at 2–8 °C. Never freeze after mixing. Keep upright, capped, and out of light.
Travel
Keep cool
Short trips at room temperature are generally fine for powder; keep mixed vials cold.
- Nasal spray form is also available.
Side effects & cautions
Reported side effects
- Mild drowsiness
- Nasal dryness
- Headache
Cautions
- Limited long-term data.
- Discuss with a doctor if you take anxiety or antidepressant medication.
