Testosterone is the male sex hormone in the body, and testosterone levels normally rise during puberty and steadily increase up until around the age of 30.
After age 30, or for some men even sooner, you start to see your levels of testosterone decline. Unfortunately, declining testosterone may impact your ability to build muscle, and you may not see the same kind of gains you saw when you were younger. By using natural testosterone support products on a regular basis you may support your body's normal hormone production. You may also see gains in strength as well.
