I'm a 37 yr old male. As part of a checkup my Dr ran a testosterone test.
I've been a little sluggish, less energy, concentration issues and less drive. Everything else was normal. My testosterone count was 275. It was on the low end, but still in the normal range. He told me that my normal may be different from another persons normal. Now...if it's the first time I have been tested...how does he know that is my normal?
