at 17 do not take any roid
because, when you are one of the unlucky ones, your legs could stop growing but your upper body not. And if this happens you are stuck with it for the rest of your life.
As for GH, i would not do it either, unless again, you are one of the unlucky guys that will get a large forhead, chin, hands, feet. Even older guys get this in their 30's even 40's.
GH is only giving at younsters when they do not grow.
You know in class at school, take the shortest guy and one is still 6 inch shorter. That one should be treated with GH.
But if you must, go for the Ox.
