Selank is a synthetic peptide developed in Russia and studied there for anxiety-related indications. A caveat worth stating plainly: the Russian clinical work used an intranasal formulation, so the injectable figure — commonly reported at 250–500 mcg per day by subcutaneous injection — is a community convention rather than a trial dose. It is quoted here as reported, nothing more. The 5 mg vial arrives as freeze-dried powder, and the label means nothing until it is dissolved in a known volume of bacteriostatic water. The table below runs that arithmetic for each common water volume, and the calculator converts any amount you enter into units on a syringe barrel.
Open the Selank calculator →| Concentration | 1 mL water | 2 mL water | 3 mL water | 5 mL water |
|---|---|---|---|---|
| 5 mg vial | 5,000 mcg/mL | 2,500 mcg/mL | 1,667 mcg/mL | 1,000 mcg/mL |
Concentration = vial contents ÷ water added. It is the same compound at every volume — more water only means a weaker solution, larger syringe marks that are easier to read, and a larger injection volume. On a standard U-100 insulin syringe, one unit is 0.01 mL at any barrel size.
