I think Cell-Tech is a bit over priced. I use San V12 and have had great results with it. A lot of guys on this board have been recommending Swole by VPX. I haven't used it, but it sounds like a similar product to the V12.
As far as fat burners (you might want to talk to a dr first as a precaution) most people use an ECA stack (Ephedra/asprin/caffiene).
