54 year-old male, trying to get fit but finding it was harder. I was slow to recover, muscles were slow to improve. I felt tired. When I went in for a physical I asked for a testosterone test. It came back "a bit low" according to the doc (about 240). Started taking 2 IC3 caps/day, because I heard it keeps T from turning into E. A month later we did a blood re-test (for other reasons) and added the testosterone test again. That time it was "normal" (over 350). I hear IC3 also helps with heart issues. So I'm taking 4 caps a day now. (Why not? They're cheap.)Feeling better, too!
