If your doc is any good, he'll insist on a blood test, and won't prescribe it unless you're low. You don't get it 'just because.'

I've been on Androgel for a few years. No noticeable side-effects. Without it, my T reading is around 100, well below the normal range. It's a pain-in-the-@55 to rub the stuff on, especially on cold mornings; so I'm only doing it a couple times a week instead of daily. That seems to get me into the low-end of normal, which is fine to me. I didn't see any big changes with it, and certainly not to my performance.
