Steroids are NOT maigc.
If you have lifted a year and have not realy seen gains, then you have other problems which steroids will NOT solve.
Most likely you are doing something wrong and it is preventing you from growing.
The most common causes are:
Your diet - protein is the building block from which muscle is made. Its like building a bridge - you need steel - right? (Carbs are fuel, that would be like the gasoline and electricity which power the machines that make a bridge). Well, if you are not eating a lot of protein you will not grow. Period.
Training - Over or under training - I just get the sense that you are following what some book told you to do, or are doing curls and presses all day .... you need to learn to train properly.
If you didn't grow that much during your first years, then taking steriods will not fix it, and will place you at undue risk--Even greater risk since its obvious that you are (probably) not training or eating correctly.
Steriods *multiply* the effects and the growth you get from proper diet and training. If you are getting near zero gains, then try multiplying anything times zero.
