cardio, diet, water... that's all you need for now...
At this age you should be able to shave off a lot of that fat easy without any drugs...
A good friend of mine I was consulting was at 230 while being 6'1". It was 6 months ago. Now he is at 180. We haven't measured his bf yet, but he, IMO, has another 10 lbs to go and then he will start put on some quality gains. He is only 19.
So, I think you can do it without drugs, but to be determined to get there. Do it naturally through hard work. Give it few months, you will see the difference...
