People will probably answer this saying stuff like don't be having steriods if you don't know what your doing and you're to young.
I want to do it so I am, that's my choice. So could people give me some good advice and info please.

Anyway, im 17 and really want to start using anabolic steriods by taking the tablets as i'm bulking at the moment.

What do they actually do? and how do they make you bigger etc?

what would be suitable to start off?

has anyone had any bad side effects?
