HGH does help in bodybuilding. One of the main benefits is increasing muscle mass. It promotes collagen synthesis, which helps develop and improve muscles. Also, human growth hormones improve bone density, which is important, especially with age. This helps to avoid injuries and fractures. In addition, it speeds up recovery from training and injuries, which is very important for any athlete. I have noticed that my energy levels and sleep quality have increased. It really helps to focus and maintain a high level of activity. If you want to learn more, I recommend checking out https://www.ecbt.org/ for more information on HGH and its benefits.
