Change in Diet to higher protein, lower fat, and mid-low carbs as well as doing a little more cardio. Possibly a 50C/40P/10F diet. Ephedra/caffiene product will help a little if you can take it and have no family history of heart problems. Also, drink a lot more water throughout the day. No steriod is going to burn the fat for you. Of course, it will help make a muscle bigger meaning larger muscle, larger caloric burn.
