dnp is easily the most effective although it is probably more dangerous than it is effective. as with any fat burner, a sound diet will make mountains of difference. t3 and clen are pretty decent as well.
sorry to say it, but winny is for me personally. some NYC/Femara/T3 etc don't hurt to stack with it though. i see results fast with winny....now with winny and fina together there seems to be a synergy. but only been on them together for less than a week so far. unless you are anti-AAS???? then ignore this all. lol.
