How Does Testosterone Promote Muscle Growth? Protein Synthesis and Hormone Levels
Testosterone and Muscle Growth : How testosterone increases protein synthesis in muscles. Why Testosterone is Key to Muscle Growth, Recovery, and Athletic Performance Testosterone plays a major role in muscle growth specifically by increasing protein synthesis . This is the process by which the body builds new proteins, primarily in muscle tissue. This occurs when testosterone binds to androgen receptors that are located in muscle cells. It then triggers a series of cellular mechanisms which both enhances and speeds up the rate at which proteins are produced. This process directly leads to the growth and repair of muscle fibers, making them thicker and stronger. It is because of this process that men who take testosterone will notice an increase in muscle size and strength and be able to recover faster from workouts. Testosterone also helps burn fat which tends to lead to men on TRT having leaner more sculpted physiques. In addition to directly stimulating protein synthesis, t...
