Only one year of training? Sorry bro, but you've got another 3 years of training to go before you should consider
steroids. That's great that you've already gained 10lbs, as you learn your body more and what works and what doesn't you can expect those gains to double during the next 1-2 years. During your first year of training your body will grow off
anything, any kind of training...even if you're doing it wrong. It's not until your 2nd, 3rd, 4th, ect.. years training that you learn what
really works and how to make your body grow. Wait until then to consider
steroids. Same goes for nutrition too, you need to learn what works for you, and what doesn't.
