Follistatin-344 peptide calculator
A 1 mg Follistatin-344 vial mixed with 2 ml of bacteriostatic water holds 0.5 mg/ml. A 100 mcg dose is 0.20 ml — 20 units on a U-100 insulin syringe — and the vial holds 10 doses of that size.
Follistatin-344 dosage chart: units to draw
Units on a U-100 insulin syringe (100 units = 1 ml) for Follistatin-344 doses from 50 mcg to 200 mcg, by how much bacteriostatic water is in a 1 mg vial. The highlighted row is the 100 mcg dose used above.
| Dose | 1 ml water 1 mg/ml | 2 ml water 0.5 mg/ml | 3 ml water 0.333 mg/ml | Doses per vial |
|---|---|---|---|---|
| 50 mcg | 5 u 0.050 ml | 10 u 0.10 ml | 15 u 0.15 ml | 20 |
| 100 mcg | 10 u 0.10 ml | 20 u 0.20 ml | 30 u 0.30 ml | 10 |
| 150 mcg | 15 u 0.15 ml | 30 u 0.30 ml | 45 u 0.45 ml | 6 |
| 200 mcg | 20 u 0.20 ml | 40 u 0.40 ml | 60 u 0.60 ml | 5 |
A 20-unit draw fits comfortably on a 0.3 ml insulin syringe (30-unit capacity), whose 1-unit (often half-unit) markings are easier to read than the 2-unit ticks on a 1 ml syringe.
Unit math only, not a dosing recommendation. The dose range is what published protocols and trials describe; see the Follistatin-344 guide for sources.
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.
- Storage for Follistatin-344: Lyophilized: refrigerated. Reconstituted: refrigerated, use within 14 days.
- For a 100 mcg dose, draw to the 20-unit mark (0.20 ml) on a U-100 insulin syringe.
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
Regulatory status: Not FDA approved. Research use only in the US.

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?
20 units on a U-100 insulin syringe, when a 1 mg vial is mixed with 2 ml of bacteriostatic water (0.5 mg/ml). That is 0.20 ml. With a different amount of water the unit count changes — the dose chart on this page lists 1 ml, 2 ml, 3 ml mixes.
How many doses are in a 1 mg Follistatin-344 vial?
10 doses of 100 mcg. The number of doses depends only on vial strength and dose size — adding more or less water changes the volume of each draw, not how many draws the vial holds.
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.
