As teenage boys get into puberty, they usually produce a lot of testosterone. This is what usually makes them behave rowdy. Testosterone usually increases muscle mass, boosts endurance, increases sexual stamina, increases bone density and boosts energy levels. Every man wants to have these characteristics. Unfortunately, testosterone levels do not usually remain high in the body. As men get into their late twenties and early thirties, testosterone levels usually go into a decline.
Testosterone therapy is meant to ensure the male body has healthy levels of this hormone. Usually, a doctor prescribes low-dose testosterone to men whose tests reveal lower than normal t-levels. The dose can be administered on a weekly basis or after every couple of days as prescribed by the doctor. The doctor will also require regular blood tests to check how the body maintains t-levels, and can adjust the dose accordingly.
