Well as far as being a pro....thats a life long comitment, LOTS of juicing, good genetics and cost tons of money. Now you have done good naturally, but theres no need for gear yet. I would spend the next 3 years researching and perfercting your diet, training and supps. Then once your a bit older decide then about messing with your hormones. As far as being a pro, well I would give that a second thought, very few make it and do serious harm to their body trying.
