Follistatin-344 peptide calculator
Pre-filled Follistatin-344 dosage and reconstitution math: a 1 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 Follistatin-344
- 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 Follistatin-344 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 100 mcg dose.
About Follistatin-344
Follistatin-344 is a synthetic follistatin peptide that binds and inhibits myostatin and activin, raising the upper ceiling on muscle growth in preclinical models. Most evidence is from animal studies.
Half-life: Approximately 30 minutes to 2 hours
Typical dose range: 100 mcg per injection (research protocols vary widely)
Class: Myostatin / activin inhibitor
Follistatin-344 calculator FAQ
Is this a Follistatin-344 peptide calculator or a reconstitution calculator?
Both. This Follistatin-344 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 1 mg Follistatin-344 vial?
This page is pre-filled with 2 ml of bacteriostatic water for a 1 mg Follistatin-344 vial because that is a common research ratio. You can adjust the water amount in the full calculator.
How many units is a 100 mcg Follistatin-344 dose?
With the default 1 mg vial and 2 ml BAC-water ratio, the preview above calculates the U-100 syringe units for a 100 mcg dose. Change the dose if your protocol uses a different amount.
Does this Follistatin-344 dosage calculator give medical advice?
No. It only performs unit math. Dosing, titration, and whether Follistatin-344 is appropriate are clinical decisions that should be made with a licensed healthcare professional.
