Thinking about taking steroids?

I am 6'1 and 14 years old. I know the side effects like it shrinks your testicles, roid rage, Baldness, Liver damage etc. But ever since i have been 10 years old i have just been dreaming to have a body like Lou Ferrigno or Franco Columbo. I am muscular for my age but i have been weight training for a bit now but no matter how my muscles are getting bigger i know i could up my game by using steroids. What is your advice to me?
