I usually use ZIP from protein factory. It's a great non stim fat burner.
I haven't actually tried any of those (I don't do a ton of fat burning cycles because I usually lean bulk) but mine usually look something like: Lipostim, Lipoflame, ZIP, Need2Slin.
Lipostim and Lipoflame are Omega's formula, pretty good shit as far as losing weight but they definitely make me a little jittery.
Also, be careful about how many stims you take......I took too many my first cut cycle and actually put on weight because I fried my nervous systems ability to burn fat.
