If your testosterone levels are that low at your age, there is some other problem causing it. (Also get your testosterone levels checked several times, as these tests are not 100% accurate every time.) You should find out what the other problem is before going down the testosterone replacement therapy (TRT) path for life. I suggest that you see an endocrinologist (I might have spelled that wrong) and have him/her run the necessary tests to find out what's going on. Good Luck Man!
