Myostatin

Myostatin is a protein produced in the body that naturally limits muscle growth by signaling muscles to stop expanding. It helps regulate muscle size, ensuring it stays balanced and healthy. When myostatin levels are reduced or its activity is blocked, muscles can grow larger and stronger, which has intrigued scientists for potential applications in medicine and athletics. However, excessive muscle growth due to low myostatin can lead to health issues, emphasizing the importance of this protein's normal function in maintaining muscle balance and overall health.
