Follistatin
Research PeptideAlso known as: FST, Follistatin-344, FS-344
What is Follistatin?
Follistatin is a protein that inhibits myostatin, a negative regulator of muscle growth, potentially allowing enhanced muscle development.
How It Works
Follistatin binds and neutralizes myostatin and activin, removing the brake on muscle growth and potentially promoting muscle hypertrophy.
What Research Shows
Key Findings:
- Myostatin inhibition promotes muscle growth in animals
- Gene therapy studies show dramatic muscle increases
- Being studied for muscular dystrophy
Limited Human Research
Most research on Follistatin has been conducted in animal models. Human clinical trials are limited or absent. Results may not translate directly to humans.
Dosing Protocol
These are general guidelines based on research literature and community protocols. Individual dosing should be determined by a qualified healthcare provider.
Safety & Risks
Reported Side Effects:
Contraindications:
- Active cancer
- Pregnancy
- Cardiac conditions
Important: This information is for research purposes only. Always consult with a qualified healthcare provider before using any peptide. Never use peptides without proper medical supervision.
Sourcing & Quality
Quality varies significantly between peptide sources. When sourcing Follistatin, consider:
- Third-party testing (HPLC, Mass Spectrometry)
- Certificate of Analysis (CoA) availability
- Purity levels (>98% recommended)
- Beware of LPS (endotoxin) contamination
