What type of contests have you done so far, if any? If it's your first, the rule of thumb is that when "you" think you are ready to step on stage, you've probably got a month of dieting left. What people usually don't understand is that there is a HUGE difference between 8%bf (being very hard) and a ripped 5%. Take a look at Homonuc.'s, Jethro',Fathead's, and even Nute's pics (his first contest and he's not even quit show ready yet), and you'll get some idea of where you need to be. I'm not trying to give you a hard time because as a teenager you look phenomenal, I just think maybe you need a reality check. Hopefully you'll appreciate this when you win the contest, "ripped to the bone"!
