The thing is, this kid is contiously asking each and every person until he finds the answer hes looking for. Well look buddy, the answer your looking for isn't the correct answer to your question. You should steer away from PH's. You know this, we all know this, so please. If your going to take them, fine go take them, but if your going to be smart than do it the right way and eat right, train right, and for gods sake supplement right.
