no xplode has a lot of caffeine in it so i'd be very careful, in fact i wouldn't take it along with a fat burner unless you space it properly and don't get too much caffeine or any other ingredients throughout the day...
i'm sure most will tell you that it's just calorie deficit and that's true... i myself have cut using no xplode in the past (successfully)...
as for fat burner, if you are able to lose fat without a fat burner, i recommend (seriously recommend), going without the fat burner... personally i'd save it until you absolutely hit a plateau...
but the best thing you could use in my opinion is an EC stack... the only problem is it's dangerous to go all out during cardio sessions because you'll find your HR racing which can't be good lol...
another problem with an ec stack is that there's a horrible rebound period when you stop it (at least in my experience), so you should consider tapering it off if you go that route...
everyone is different, that is just my personal experience...
i had bad withdrawls from EC stacks and i found a method that works for me... here's a thread i wrote about my experience
