This is one of the reasons roid heads piss me off. Most of the replys here have been to get girls, respect from guys, etc...
There should be three answers given.
1. I started for myself, my choice, my decision
2. I've been training for years and gains had stopped, which meant it was time to gear up.
3. To increase athletic performance in a sport
I mean shit, if the only reason you are putting drugs into your body is to impress girls, than I personally think you're pathetic.
