Definitely. Whenever I was younger I actually had to take prescription steroids to help boost my immune system twice. First time I was about 11, and gained 14 pds in about 14 days LOL. Mainly in my cheeks!!!! Went down after a while though...
Second time, I actually lifted then, and was like NO WAY I'M GAINING WEIGHT THIS TIME! So, worked out like crazy with them, and never gained a pound. I was on them about 2 wks that time as well....I dunno about the illegal kind, but the prescription kind drove me INSANE! They make you so mean, and aggressive, eat like your going to hybernate for the winter. Told my doctor I couldn't go to school while I was on em cuz I didn't know what I'd do LOL. He had no trouble taking me out of school for a lil while .
After taking those I don't see how people control that. It's no wonder people kill others, kill themselves, etc on them. Think you'd have to play some football, and run over top of people to get the aggression out of your system. Would never be worth it to me. Also, people do not realize that no matter what your on (creatine, steroids, protein, cell-tech, etc) you do have to work out with it. So, even the people who have taken steroids such as Arnold...I don't completely disregard them. He actually had to work for what he got, just took a dumb shortcut to get it. If there able to take the negative effects that they cause (anger, health probs, etc) then more power to them.
