Muscle · Myostatin Inhibition

Follistatin 344

Myostatin-binding protein fragment researched for muscle growth.

Mechanism of Action

A naturally occurring glycoprotein that binds and neutralizes myostatin and activin, releasing the natural brake on skeletal muscle growth in preclinical models.

Research Areas

Muscular dystrophy models

Skeletal muscle hypertrophy

Age-related sarcopenia (preclinical)

Common Research Protocols

Subcutaneous research dosing

Short cycles in animal hypertrophy studies.

Protocols summarized for educational reference from published research. Not dosing guidance.

Cited Research

[1]Science Translational Medicine·2009

Follistatin gene delivery enhances muscle growth and strength

Demonstrated durable hypertrophy in primate models.

Important Considerations

•Off-target effects on activin signaling (reproductive, cardiac) are a concern.
•Not FDA-approved; banned by WADA.
