Selank reconstitution calculator.
Work out the concentration of a reconstituted Selank vial. Presets match the 10 mg format we stock, and the reference table below is calculated for those exact vials. Research use only.
This tool reports concentration only. It is not dosing guidance, and nothing here is for human use.
Selank concentration reference table
Every combination of the Selank vial sizes we stock and the bacteriostatic water volumes people most often add.
| Vial | BAC water | Concentration | Per 100 µL aliquot |
|---|---|---|---|
| 10 mg | 1 ml | 10 mg/ml | 1 mg (1,000 mcg) |
| 10 mg | 2 ml | 5 mg/ml | 0.5 mg (500 mcg) |
| 10 mg | 3 ml | 3.333 mg/ml | 0.333 mg (333 mcg) |
| 10 mg | 5 ml | 2 mg/ml | 0.2 mg (200 mcg) |
How the calculation works
Concentration is the mass of peptide divided by the volume of solvent. A vial holding 5 mg reconstituted with 2 ml of bacteriostatic water gives 2.5 mg/ml, so a 100 µL aliquot contains 0.25 mg. The powder itself adds no meaningful volume at these masses, which is why the water volume alone sets the concentration.
Handling in the Vietnamese climate
Sealed lyophilized vials are stable at room temperature in transit, which is why the material ships dry rather than cold. Once reconstituted, the solution is kept refrigerated and shielded from light. Bacteriostatic water is the usual solvent because the benzyl alcohol in it lets a vial be entered more than once.
What is Selank?
A synthetic peptide derived from an immune fragment, studied for anxiety pathways.
Selank is a synthetic heptapeptide built from tuftsin, a small fragment of an antibody molecule that the immune system produces naturally. As with Semax, a Pro-Gly-Pro tail was added to keep enzymes from clearing it too quickly.
It came out of the same Russian research programme as Semax and is registered in Russia only. Research attention focuses on GABAergic and serotonergic signalling, anxiety-related pathways. It is supplied as a lyophilized powder vial; a nasal spray is something the buyer prepares themselves by reconstituting the powder and transferring the solution to a spray bottle.

Common questions
What is Selank?
A synthetic heptapeptide based on tuftsin, a natural immune-system fragment, with a Pro-Gly-Pro tail added for stability. It was developed in Russia and is registered there only. Listed here as a non-clinical research material.
How is Selank different from Semax?
Both come from the same Russian programme and use the same stabilising tail, but Selank derives from the immune peptide tuftsin while Semax derives from ACTH. Selank research centres on anxiety-related signalling; Semax research centres on BDNF.
How much bacteriostatic water do I add to a Selank vial?
There is no single correct volume. The water volume sets the concentration: more water gives a weaker solution and a larger aliquot for the same mass. Common choices are 1 to 5 ml. Enter your vial size above to see what each volume produces for 10 mg.
What concentration does a Selank vial give?
It depends entirely on the solvent volume. The reference table above lists every combination of the 10 mg vial format and 1, 2, 3 and 5 ml of bacteriostatic water.
Does the powder change the final volume?
Not measurably at these masses. A few milligrams of lyophilized peptide occupies a negligible volume, so the bacteriostatic water you add is effectively the final volume.
Can I use normal water or saline instead?
Bacteriostatic water is the standard solvent for multi-entry vials because it contains a preservative. Sterile water and saline have no preservative, so they are single-entry solvents.
