Follistatin is a naturally occurring protein that plays a vital role in regulating muscle growth, fat metabolism, and tissue repair. By inhibiting myostatin, a negative regulator of muscle growth, follistatin can significantly promote muscle development and recovery. This makes it a popular supplement in the fitness and bodybuilding communities. Beyond muscle growth, research also suggests its potential in improving healing processes and even combating certain age-related conditions. Follistatin supplementation offers promising benefits for those looking to enhance their physical performance and overall health.
