Out of curiosity, why would you do something that you know is so bad for you? Are you that unhappy with the way you look?
Most men and women prefer the look of a non-freaky physique. If you're doing it to feel stronger / tougher or whatever you want to call it, just remember that a handgun in the hands of a 100lb 15 year old will take you out in 2 secs flat. If your an olympic powerlifter or WSM competitor, maybe, otherwise, I just don't get it. You can build a great physique naturally, why bother with drugs?
Don't get me wrong, if they weren't unhealthy, I'd use them. But only to a certain point -- as a shortcut. I'll get there naturally though, it's just going to take longer.
