follistatin 344
Follistatin 344 is a glycoprotein that acts as a potent inhibitor of the TGF-β superfamily, specifically binding to and neutralizing myostatin and activins. By inhibiting myostatin, a protein that limits muscle growth, it promotes significant muscle hypertrophy and has shown potential in reducing adipose tissue mass.
Lab Notes — Research Studies
01 Systemic administration of Follistatin288 increases muscle mass and reduces fat accumulation in mice
This study demonstrates that systemic administration of follistatin increases lean body mass, promotes muscle fiber hypertrophy, and significantly decreases body fat mass.

⚗️ Effects
- Myostatin Inhibition: Highly effective at temporarily overriding genetic limits on muscle growth.
- Cycle Longevity: Effectiveness often peaks early; many users find gains are difficult to maintain without continued use or strict training.
- Potency Issues: User consensus suggests that many 'Follistatin' products on the market are underdosed or fake, leading to inconsistent results.
💉 Dosage & Administration
- Common Cycle: 100mcg to 300mcg per day is frequently cited by experienced users.
- Loading Phase: Some users suggest a higher initial dose for 10 days followed by a maintenance period.
- Site Injection: There is debate among users whether localized injections provide better results in specific muscle groups versus systemic effects.
⚠️ Side Effects
- Tendon Weakness: Research suggests muscle growth may outpace tendon strength, leading to potential injury.
- Joint Pain: Some users report increased stiffness or discomfort in joints during peak muscle growth phases.
- Appetite Fluctuations: Significant shifts in hunger levels are common as metabolism changes.
📦 Availability & Sourcing
- Research Chemicals: Primarily sold through research chemical vendors and not approved for human consumption by the FDA.
- Legality: Generally legal to purchase as a lab-grade chemical in most jurisdictions, but banned by WADA and most professional sports organizations.
Reaction Log — User Experiences
Users generally report impressive muscle gains, but opinions are split due to high costs, short-lived results after cessation, and concerns regarding the authenticity of available products.
