What is the point of using steroids if all your gains disappear as soon as you stop taking them? And you can't take them for more than a couple of months at once due to the health issues. To quote Greg Zulak from his old Q&A in MuscleMag:
"Steroids are borrowed muscle. It is a bargain with the the devil: you get muscles in exchange for your health and you will only keep getting muscles for as long as you hold up to your side of the deal with the devil by giving your health in exchange for the muscles. As soon as the deal is of, your muscles evaporate and the muscle you are left with is the one you got through hard training."

your oversimplifying.........
its not a zero sum thing where your gains dissapper the minute you stop taking shit
if you go on for 3 months, and put on 20 lbs............assuming you keep your diet and training right, your not just going lose 20 lbs of muscel when you go off
if you go off for an extended period of time.........you will soften up a little and lose 7...........but that still over 10 lbs up from where you started
