I'm definitely looking for something with no stim (or as little as possible). I still remember the one time (long ago) that I tried a fat burning product it had a lot of stim and I felt as if I wanted to bounce of the walls, which in some (but not all) ways can be good -- until you want to go to sleep and it becomes a big problem.
I'll research the Alpha T2 on the boards here since it seems to be so popular. Also the Lean Extreme and Forged Burner.
Can't hurt to check out some info on Need2Slin and the NTBM Am/pm Thermo Fat Blaster Stack either.
Thanks for all the replies and, if you have more suggestions, keep them coming.
