I'm with ya badazzwhitedude,
The average man loses 50% of his testosterone between 50 and 70 years of age and moderate amount of testosterone could increase both his muscular strength and sexual functions. The only concern is that extra testosterone may cause a preexisting prostate cancer to spread through the body.
also if I were you I would do an annual blood test on Prostate specific anti-gen (an indication if you can get cancer in the near or far future) if it was higher than 6, then Testosterone therapy should never at any way be given
beside that, at least every 3months a blood test including the following Blood pressure, Cholesterol/HDL,
Hematocrit , Liver function tests especially Gamma GT
