Follistatin 344 — 1mg
🧬 Myostatin Inhibitor | Growth Factor Modulator
💉 Form: Lyophilized Powder for Reconstitution
Description
Follistatin 344 is a potent myostatin-binding protein fragment that promotes muscle hypertrophy by inhibiting negative regulators of muscle growth such as myostatin and activin A. Used in research for its role in anabolic signaling and tissue regeneration.
🧪 Form and Storage
– 💉 Form: Lyophilized powder in sterile glass vial
– 🧊 Storage: Store refrigerated at 2–8°C
– 🕒 Stability: After reconstitution, stable for 20–30 days if kept sterile
– ⚠️ Do not freeze
– 🔁 Multi-use compatible with bacteriostatic water
🔬 What is Follistatin 344?
Follistatin 344 is a recombinant human protein fragment derived from follistatin, a binding glycoprotein that neutralizes myostatin, thereby lifting the brake on muscle growth. Its action extends to inhibiting activin A and B, making it a candidate for muscle-wasting therapy and performance enhancement. Primarily researched in anabolic and regenerative medicine settings.
✅ Benefits of Follistatin 344
● Inhibits myostatin, allowing unregulated muscle development
● Stimulates lean muscle hypertrophy without androgenic side effects
● Supports tissue recovery and musculoskeletal regeneration
● Non-hormonal pathway, making it synergistic with other agents
● Potential role in treating muscle atrophy, sarcopenia, and cachexia
● Promising in anti-aging and regenerative peptide protocols
⚠️ Possible Side Effects
● Injection site redness or swelling
● Unregulated muscle growth in supraphysiologic dosing
● Unknown long-term safety in humans
● ⚠️ Research use only — not approved for human consumption
● Potential interaction with hormonal systems (e.g., FSH suppression)
📏 Dosage Guidelines
● Research dosage: 100–200 mcg/day or 1mg/week
● Cycle duration: 10–20 days or pulsed every 3–4 weeks
● Route of administration: Subcutaneous (SC) or Intramuscular (IM)
● Example: 200 mcg daily for 5 consecutive days, then pause
🧼 Best Practices
● Reconstitute with bacteriostatic water (1–2ml recommended)
● Maintain sterile technique for all handling and injections
● Do not shake vial — gently roll to dissolve
● Inject at the same time daily for consistent exposure
● Discard vial if solution becomes cloudy or contaminated
🧠 Lifestyle and Dietary Considerations
● Combine with intensive resistance training and high-protein intake
● Emphasize deep sleep and stress reduction for growth optimization
● Avoid alcohol and estrogenic compounds that may interfere
● Supplement with creatine, omega-3s, and micronutrients
● Consider cycling or stacking with GH secretagogues (e.g., CJC-1295, Ipamorelin)
