Selank was developed in Russia as an anxiolytic peptide and has published human studies in generalised anxiety, mostly intranasal. As with Epithalon, the literature is regionally concentrated and lightly replicated elsewhere.

Every figure on this page is a range reported in published literature or in a publicly documented study protocol. It is a record of what researchers used, not a recommendation, a therapeutic protocol, or advice. Peptide Intel Hub is an independent publication, sells nothing, and describes these compounds as in-vitro research reagents only.
Each row below describes one body of work. The model and population are part of the figure — a rodent per-kilogram quantity and a human trial quantity are not comparable.
Drops per nostril rather than milligrams is how the source protocols express this.
Elevated plus-maze and open-field behaviour are the standard readouts.
These figures match the published chart for this compound on peptidedosages.com, including the reconstitution volume, resulting concentration, insulin-syringe units and the staged schedule. Educational reference only — not instructions, and not medical advice.
Selank · 10 mg Vial
This Selank dosage chart explains how a 10 mg vial can be calculated for intranasal research with a verified 0.10 mL metered actuator. Published human Selank studies primarily used intranasal drops or measured intranasal solution. A measured 5 mL final volume provides 200 mcg per spray, while a measured 10 mL final volume provides 100 mcg per spray.
| Measured Final Volume | Vehicle Added After Transfer | Final Concentration | Per Verified 0.10 mL Spray |
|---|---|---|---|
| 5.0 mL | About 2.0 mL | 2,000 mcg/mL | 200 mcg<br>50 nominal sprays |
| 10.0 mL | About 7.0 mL | 1,000 mcg/mL | 100 mcg<br>100 nominal sprays |
The same arithmetic for every vial size Selank is supplied in, using a fixed 3 ml of bacteriostatic water. One unit on a U-100 insulin syringe is 0.01 ml, so the unit column below is simply the volume that carries the reported amount. Educational arithmetic only — not instructions, and not medical advice.
Selank · 3 ml bacteriostatic water
| Vial size | Concentration | Per 1 unit |
|---|---|---|
| 5 mg | 1.67 mg/ml | 17 mcg |
| 11 mg | 3.67 mg/ml | 37 mcg |
No single reported amount applies to this compound, so only the concentration and the value of one unit are shown. Only the vial sizes this compound is actually supplied in are shown, and every figure assumes exactly 3 ml of bacteriostatic water. For any other volume, use the reconstitution calculator.
A 10 mg vial in 2 mL of bacteriostatic water gives 5 mg/mL, equivalent to a 0.5% solution before dilution.

Each one describes what researchers administered, in which model or population, and over what period. Quantities reported in a study are specific to that study's design and are not transferable guidance.

62 patients with generalized anxiety disorder and neurasthenia received Selank (dosing per Russian regulatory protocol, intranasal) compared against the benzodiazepine medazepam to assess anxiolytic efficacy.
