I fear I might lose interest in lifting. Progress is fun because I have average genetics, but I am doing OK with those. So, for relativity, I can look at average people and their results. Taking steroids put you into a race where you will be compromising your health, and results quickly become dose rather than work dependant.
On the other hand, I might respond really well...some people do. Or really bad. Who knows. As long as you're enjoying what you're doing, do it. The thing about steroids is if you take them you will be "clean" again, but never 100 % natural.
