Follistatin 344 Common Research Ranges
| Phase | Dose (mcg/day) | Frequency | Duration | Use Case |
|---|---|---|---|---|
| Research loading | 100-300 mcg | Daily | 10-20 days | Initial protocol, muscle growth focus |
| Extended research | 100-200 mcg | Daily | 20-30 days | Sustained myostatin inhibition |
| Lower-dose exploratory | 50-100 mcg | Daily | 10-15 days | Conservative starting approach |
| Maintenance | 50-100 mcg | 2-3x/week | Ongoing | Lower-frequency ongoing research |
Key Properties
- Half-life: approximately 35 hours (supports once-daily dosing)
- Mechanism: binds and neutralizes myostatin (GDF-8) and activin A
- Route: subcutaneous injection in research settings
- Legal status: not FDA-approved — research only, extreme caution
- Cycle break: 4-8 weeks off between research cycles
- WADA bans myostatin inhibitors at all times for tested athletes (wada-ama.org)
- This calculator performs math conversions only — it does not verify product quality, safety, or medical appropriateness
Reconstitution Calculator
Calculate how much bacteriostatic water to add and how many units to draw on your syringe for your Follistatin 344 dose.

How Reconstitution Works
- Determine concentration: Divide peptide amount by water volume (e.g., 1 mg ÷ 1 mL = 1 mg/mL = 1000 mcg/mL)
- Calculate draw volume: Divide your dose by concentration (e.g., 100 mcg ÷ 1000 mcg/mL = 0.1 mL)
- Convert to syringe units: Multiply mL by 100 for U-100 syringes (0.1 mL = 10U)
- Verify syringe capacity: Ensure the draw volume fits your syringe
Example Calculation
Vial: 1 mg Follistatin 344
Water: 1 mL bacteriostatic
Dose: 100 mcg
Syringe: 100U (1 mL)
Concentration: 1 mg ÷ 1 mL = 1000 mcg/mL
Draw volume: 100 mcg ÷ 1000 mcg/mL = 0.1 mL = 10U on a U-100 syringe
Follistatin 344 Dosage Calculator
If you are searching for a follistatin 344 dosage calculator, you may be trying to organize a myostatin inhibitor protocol into a clear plan. This calculator helps with the math — concentration, draw volume, syringe units, and phase-based scheduling. It does not provide medical recommendations or verify that peptide use is safe or appropriate for you. No safe human dose for follistatin 344 has been established.
What is Follistatin 344?
Follistatin 344 (FST344) is an isoform of follistatin, a naturally occurring glycoprotein that binds and neutralizes myostatin (GDF-8) and activin A. Myostatin is a protein that normally limits muscle growth. By inhibiting myostatin, follistatin 344 has shown dramatic muscle hypertrophy in animal studies, including permanent muscle changes from single gene therapy doses. The compound has an approximate half-life of 35 hours and is administered via subcutaneous injection in research settings.
Research dosing patterns
Research community discussions typically describe four protocol phases. The loading phase uses 100 to 300 mcg per day for 10 to 20 days. An extended phase runs 20 to 30 days at 100 to 200 mcg daily. A lower-dose exploratory approach uses 50 to 100 mcg daily for 10 to 15 days. A maintenance phase at 50 to 100 mcg, 2 to 3 times per week, may follow. A cycle break of 4 to 8 weeks off is typically observed between research cycles. These patterns are not FDA-approved clinical guidelines.
Safety and limitations
Follistatin 344 is not FDA-approved for any therapeutic use. Human pharmacokinetic and safety data are extremely limited. Animal studies showing permanent, irreversible muscle hypertrophy raise significant concerns about uncontrolled effects in humans. Because follistatin interacts with multiple TGF-beta family members beyond myostatin, off-target effects are possible but not well characterized. Commonly reported side effects in research settings include injection site reactions and mild nausea.
Anti-doping considerations
Myostatin inhibitors, including follistatin, are prohibited by WADA at all times for tested athletes. USADA lists myostatin inhibitors as banned substances in and out of competition. If you compete in a tested sport, using follistatin 344 may result in anti-doping violations regardless of how it was obtained. (wada-ama.org)
Important limitations
This calculator performs math conversions only. It does not verify product quality, sterility, label accuracy, or medical appropriateness. Peptide products can vary in strength, purity, and storage conditions. No safe human dose has been established. Any use should be discussed with a licensed healthcare provider. Do not use if pregnant, breastfeeding, or have a history of muscle or neurological conditions without clinician guidance.
