About a year ago I went in to the Dr and had a physical as part of it they tested my testosterone. At that time it was low and we had a second test because my white blood cell count was low as well so they wanted to rule out cancer. A year later with added weight lifiting to weekly workouts my testosterone level has increased to 290 ng/dL. I am in the normal level now but way below the average with level of 679 ng/dL. I am 36 years old and wanted to see what levels other people are at. I do seem to be slowing down as I age by a good bit just not sure if it all has to do with age or other stuff.
