How steroids boost energy in athletes?

Steroids boost energy in athletes primarily by increasing the production of red blood cells, which enhances oxygen delivery to muscles during intense physical activity. They also promote muscle growth and improve recovery times, allowing athletes to train harder and more frequently. Additionally, steroids can elevate levels of certain hormones, such as testosterone, which can further enhance strength and endurance. However, the use of steroids carries significant health risks and is banned in competitive sports.
