Selank, 7 amino acids, 751.9 g/mol.
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.
Modulates GABA signaling, enkephalin breakdown, and serotonin/BDNF expression; also influences cytokine balance.

Clinical studies in anxiety/neurasthenia showed benefit.
Commonly reported, no sedation or dependence in studies.
Cytokine effects seen in lab studies.
“Anecdotal” means reported by users, not shown in controlled trials. Sources
Not recommendations. These are commonly cited ranges, shown so you can see what real-world use looks like.

Set up for Selank. Switch vial size any time. Educational math only, not dosing advice.
At a common mix of 5 mg of Selank in 2 mL of water (2.5 mg/mL), these commonly reported doses come to the following on a U-100 insulin syringe (100 units = 1 mL). They are examples of the arithmetic, not recommendations.
| Reported plan | Dose | Draw to | Volume |
|---|---|---|---|
| Standard | 300 mcg | 12 units | 0.12 mL |
Concentration (mg/mL) = vial mg ÷ mL of water; units = dose (mg) ÷ concentration × 100. A different vial size or amount of water changes every number above.

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.
Approved as a medicine in Russia; unapproved in the US and most Western regulators.
Regulations change often — verify with the FDA, EMA, MHRA, Health Canada, TGA and WADA before acting.
Studies and Russian clinical use report no dependence or withdrawal, but data is limited.
It depends on the mix. At a common mix of 5 mg of Selank in 2 mL of water (2.5 mg/mL), 300 mcg is 12 units (0.12 mL) on a U-100 insulin syringe. The formula is dose in mg ÷ concentration in mg/mL × 100. Change the vial size or water in the calculator and the units update. This is math, not a dose recommendation.
Bacteriostatic water (0.9% benzyl alcohol) — allows multiple draws from one vial. A common mix is 5 mg + 2 mL, which gives 2.5 mg/mL. Less water makes a stronger mix and fewer units per dose; more water makes a weaker mix and more units. Pick the amount that lands your dose on an easy-to-read line.
Refrigerate at 2–8 °C. Never freeze after mixing. Keep upright, capped, and out of light. Plan on about 21 days once it is mixed, and discard it sooner if it turns cloudy or has particles. The calculator shows how long a vial lasts at your dose and flags a vial that outlasts its shelf life.
Evidence rating (3/5): Small Russian clinical trials in generalized anxiety; limited Western data.
Legal status: Approved as a medicine in Russia; unapproved in the US and most Western regulators.
