Lets not forget the human body doesn't fully stop growing until around 25. Juice can fuse growth plates. Don't think that because your as tall as your gonna get that your done growing, you start to grow width as well. Shoulder to shoulder size will continue to grow. How dumb would it be to use roids for a better body but screw your shoulder width, then your never gonna have a v-taper. Not to mention one leg could have grown a little more then anotyher and it hasn't had time to catch up yet. This may not be noticeable to the eye, but it will really fuck up symetry, you just won't put on mass even. It's like having a back alignment problem.
