Frequently asked questions
How do I calculate Selank dose per spray?
Add your bacteriostatic water and saline for the total volume, divide the Selank amount by that total to get the concentration, then multiply by the pump volume (commonly 0.1 mL). For a 10 mg vial in 3 mL total, that is 3.33 mg/mL, so each 0.1 mL pump delivers about 333 mcg.
What vial sizes does Selank come in?
Selank is commonly supplied as 5 mg, 10 mg. The amount in the vial does not change with how much water you add — water only sets the concentration.
Is Selank approved for human use?
