The only legal fat burning supplement I've ever taken that produced results was Lipokinetix back in 2002. Usnic Acid, T-2, Ephedrine, Caffeine and Yohimbine. Placebo effect or not I had no cravings for junk, felt warm all day, didn't lose any muscle or strength and got my bodyfat down to an all time low. I'm curious as well as to how the more "modern" supplements, the ones you mentioned and seasapure, compare to Lipo. For now its just a pot of coffee and cardio.
