Do go to the DR. You'll have to ask specifically for a testosterone test. You won't be able to take T for the rest of your life. Your red blood cells will build in your body, ie blood clots. Not to mention it will significantly raise your chance of prostate cancer. I was on it for some years and it made a huge difference, but now I'm not because of risk and blood work results. Diet and physical training is great advise, but you never know you could have something else going on. The Dr. should be able to figure out best route.
