Hi I'm 21 years old and I've been noticing for a while that I've been extremely fatigued. It doesn't matter how much hours of sleep I get I'm still tired. So I did some research on low testosterone and the symptoms they listed is what I'm currently experiencing the low energy, constant fatigue, lack of facial hair, mood changes. I visited my doctors and he gave me some general lab orders, the results came back fine then I asked him for a testosterone test. The staff at my doctors office called me a few days later and said I'm in the normal limit for testosterone, so I requested a copy of the report. My results were 481 ng/dL and the limit is between 348-1197 ng/DL. My question is should I push for treatment because I'm towards the lower end of the margin and it could decrease as I grow older or should I leave it alone?
