Frequently asked questions
How much bacteriostatic water should I add to Selank?
For a 5mg vial of Selank, add 2ml of bacteriostatic water. This concentration works well with a standard insulin syringe.
What is the typical Selank dosage?
Typical research dosages for Selank range from 250 to 750 mcg, administered 1-2x daily, intranasal or subcutaneous.
How long does reconstituted Selank last?
Reconstituted Selank should be stored at 2-8°C refrigerated and used within 21 days. Unreconstituted vials can be stored for up to 24 months.
How do I calculate my Selank dose?
Divide your target dose by the concentration to get the volume, then multiply by 100 for units on a U-100 insulin syringe. For example, a 5mg vial in 2ml of bacteriostatic water gives 2500 mcg/ml. The calculator above does this automatically once you enter your vial size, water volume, and desired dose.
How many units of Selank should I draw on an insulin syringe?
On a U-100 insulin syringe, 1 unit equals 0.01 ml regardless of the barrel size (0.3ml, 0.5ml, or 1ml). Enter your reconstitution details in the calculator to see the exact number of units to draw for your dose.
