I mean this with your benefit in mind: You have no idea what you are talking about on so many levels. Your brother is even more clueless. You can seriously hurt yourself, and the truth is you will not gain any significant muscle if you use steroids. You will gain some water weight and possibly develop small breast we call gyno. Your testicules will shrink and you may not be able to get an erection.
What you need to do is:
1- Forget about steroids
2- Join a gym
3- Pick up Flex Magazine, read the training and diet info and discard the supplement info, you don't need them
4- Plan a schedule and stick to it.
