Sermorelin peptide calculator
Pre-filled Sermorelin dosage and reconstitution math: a 3 mg vial, 2 ml of bacteriostatic water, and the resulting U-100 insulin-syringe units. Adjust the inputs below or open the full calculator.
How to reconstitute Sermorelin
- Wipe both vial stoppers with a fresh alcohol swab and let them dry.
- Draw 2 ml of bacteriostatic water into a syringe.
- Insert the needle at an angle into the Sermorelin vial and let the water run slowly down the inner wall — do not inject directly onto the powder.
- Do not shake. Gently swirl the vial until the peptide fully dissolves.
- Store the reconstituted vial refrigerated (2–8 °C / 36–46 °F) and use within roughly 28 days.
- Draw each dose to the unit mark shown above for your target 200 mcg dose.
About Sermorelin
Sermorelin is a truncated 29-amino-acid analog of endogenous growth-hormone-releasing hormone (GHRH). It stimulates the pituitary to release GH in a physiological, pulsatile pattern.
Half-life: Approximately 10–20 minutes
Typical dose range: 100–500 mcg per injection, typically at bedtime 5 days per week
Class: Growth hormone-releasing hormone analog (GHRH 1-29)
Sermorelin calculator FAQ
Is this a Sermorelin peptide calculator or a reconstitution calculator?
Both. This Sermorelin calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
How much bacteriostatic water for a 3 mg Sermorelin vial?
This page is pre-filled with 2 ml of bacteriostatic water for a 3 mg Sermorelin vial because that is a common research ratio. You can adjust the water amount in the full calculator.
How many units is a 200 mcg Sermorelin dose?
With the default 3 mg vial and 2 ml BAC-water ratio, the preview above calculates the U-100 syringe units for a 200 mcg dose. Change the dose if your protocol uses a different amount.
Does this Sermorelin dosage calculator give medical advice?
No. It only performs unit math. Dosing, titration, and whether Sermorelin is appropriate are clinical decisions that should be made with a licensed healthcare professional.
