Holy shit you're a big dude. Cardio and proper diet are going to have to be the first and foremost things that your concerned about.
AAS aren't necessarily going to help you get rid of your gut (though some say
tren burns fat, etc). What they will help with, is retaining muscle as you're burning fat w/ your cardio and diet. If you're looking for the right drugs to aid in the fat burning process, you might want to look into things like
clen, T3, or DNP. I'll be the first to admit that I have never used any fat burning drugs as I can usually keep my fat levels under control w/ proper diet and nutrition, so I really couldn't provide any advice on these drugs.
