GDF-8 (Growth Differentiation Factor 8)

GDF-8, also known as myostatin, is a protein that plays a key role in regulating muscle growth. It acts as a natural brake, preventing muscles from growing too large. When GDF-8 is active, it helps maintain muscle balance and prevents excessive muscle development. Conversely, reducing GDF-8 activity can lead to increased muscle mass, which is being explored for potential treatments for muscle-wasting diseases. Overall, GDF-8 is essential in controlling muscle size and ensuring proper muscle function.
