The choice referring to increased muscle mass and fat metabolism is accurate because human growth hormone (HGH) plays a crucial role in promoting growth, cell repair, and metabolism. When HGH is released in the body, it stimulates the production of proteins, which leads to an increase in muscle mass. Additionally, HGH enhances the body’s ability to metabolize fat, thus improving overall body composition by reducing fat stores.

This dual effect of boosting muscle growth while facilitating the utilization of fat for energy contributes to physical performance and can help individuals achieve better body composition. Many athletes and individuals seeking to improve their fitness may look to HGH for these benefits, emphasizing its importance in physical training and rehabilitation contexts.
