Steroids themselves do not make you lose fat directly. #1 is the diet. #2 is the cardio. #3 is fat burners. Steroids help you to maintain muscle when you are cutting and when you are lean, they give you a more dramatic look, ie, drier, harder, more grainy. 

So clen would be the number one thing for fat loss. Then T3 would be the next step, combined with steroids to protect muscle from breaking down. 

On the topic of hardeners, the bread and butter stack would be test and an AI to control water, along with tren and masteron. But I have also seen guys run this combo without looking great, mainly because they never had their diet and cardio right to begin with. So dont expect the gear to do all of the work. To get really shredded, you are going to need to diet hard and add as much cardio as needed. Then the fat burners will help and the steroid stack will give you that dry, veiny look you are after
