Frequently asked questions
How much bacteriostatic water should I add to Sermorelin?
For a 2mg vial of Sermorelin, add 2ml of bacteriostatic water. This concentration works well with a standard insulin syringe.
What is the typical Sermorelin dosage?
Typical research dosages for Sermorelin range from 200 to 500 mcg, administered 1x daily before bed.
How long does reconstituted Sermorelin last?
Reconstituted Sermorelin 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 Sermorelin 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 2mg vial in 2ml of bacteriostatic water gives 1000 mcg/ml. The calculator above does this automatically once you enter your vial size, water volume, and desired dose.
How many units of Sermorelin 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.
