A great stack that I've used for belly fat loss was using cardarine known GW-51516 and ligandrol, even s4 if you can afford it just in the anabolics/ ppar antagonist category. Then throw in some yohimbe at 0.2mg/kg body weight, l-carnitine (preferably evogen carnigen), then a moderate stim based burner then fasted cardio (low intensity steady state). Then mode of a 'blood and guts' Dorian style training at night followed by more low intensity cardio. Of course you need to Taylor your diet to put you in a fat burning state specifically instead of just calorific deficit in general, but that's something to tackle in the nutrition forums.. That's just my personal preference in what has produced the best results for me
