"I am a 65 year old male who was diagnosed with Low Testosterone. The reading was 146 when it was supposed to be between 400 to 600 for normal range. After 2 months of weekly injections my reading is now 450. I feel better than I have felt since I was in my 30&#039;s and my doctor says I may have had this problem for years. One side effect I have noticed is I am beginning to grow a nice stand of hair on my chest and belly which looks rather manly."
