At this age it is a horrible idea to use steroids. Perhaps you will not experience all that many side effects, but on the long run steroid use will affect your development, and will definitely affect your natural testosterone production. Besides, it does not make all too much sense to use steroids at such an age, when your body is not completely developed yet. You should be using steroids in those times when you reach a growth plateau, and can't grow anymore without a little kick. Keep in mind that the more you use steroids, the less effects they will give you, so you will end up with steroids barely helping you in those moments when you will really need them. Therefore, better wait off - at this age all you need to grow is eat plenty of healthy food, and exercise a lot. Let the mother nature do the rest.
