Celly you are not much older than he is. Also, and this may not have been the case for you, the majority of 17 year olds have jobs and generally provide for themselves (outside of food, shelter, etc.)
You always come off a little holier than thou in threads such as these man, I know it isn't your intention but it almost always happens.
OP, to answer your question. You could probably use it without any ill effects but it is not advisable to use any supplements at your age. Protein, vitamin, and creatine at the most. And as cel already stated it often leads to the belief that one cannot make progress without additional supplementation, which is not true.
