🔬 Product Overview

Follistatin 344 (FST344) is a naturally occurring glycoprotein known for its potent role in inhibiting myostatin—a protein that suppresses muscle growth. By binding to myostatin and activin A, FST344 blocks their biological activity, promoting muscle hypertrophy and regeneration.

FST344 is being actively studied for its applications in muscle-wasting disorders, athletic recovery, regenerative medicine, and age-related muscle loss (sarcopenia). The 344-amino acid version is preferred for systemic circulation due to its extended half-life.

⚙️ Key Features

• ✅ 1mg research-grade lyophilized peptide

• ✅ Direct inhibitor of myostatin and activin A

• ✅ Supports muscle growth and regeneration

• ✅ HPLC verified ≥98% purity

• ✅ GMP-compliant synthesis with CoA included

• ✅ Ideal for long-term in vivo or in vitro studies

📚 Mechanism of Action

Follistatin 344 functions by binding to and neutralizing myostatin and activin A, members of the TGF-β (transforming growth factor-beta) superfamily. By blocking these molecules, FST344 disrupts their negative regulatory effect on skeletal muscle, leading to:

• Enhanced muscle fiber size

• Reduced muscle atrophy

• Accelerated tissue regeneration

• Anti-inflammatory and anti-fibrotic effects

🔬 Research Applications

💪 Muscle Growth & Hypertrophy Studies
Ideal for investigating sarcopenia, cachexia, muscular dystrophy, and athletic performance enhancement.

🧬 Tissue Repair & Wound Healing
Studied for regenerative effects in skeletal muscle, skin, and organ systems.

🧫 Aging & Longevity Research
Used in anti-aging studies related to muscle preservation and hormone modulation.

🧠 Neuroprotective & Anti-Inflammatory Roles
Emerging data suggests activity in neuroinflammation models.
