You posted almost the exact same thing in your last post title "stunted growth". If you feel you need steroids at 18, go ahead stunt your growth and mess up your endocrine system. You'll be muscular for a few weeks (it won't last of course because you have no idea what you're doing) but those few weeks will be totally worth it. Then you'll be able to tell all your friends "yeah, I did 'roids', it was pretty sweet". Is that what you want to hear? numbnutz.
