I have tried many other diet pills. The one that worked the best was metabolife 360 with ephedra but they no longer make it and i heard someone talking about how they bought over the counter t3 pills and they said they worked great. I've also read on the forums that they work really well, but that you're only supposed to take them for like 2 weeks. i guess some work better than others and i know they sell T3 pills at GNC, but i heard they don't really work. I'm just a little skeptical about the over the counter diet pills. I wanted to try hoodia but then i read in a magazine that the FDA is a couple yrs away from approving the formula that was bragged up on 60 min and oprah. The ones out now are just supposed to be copy cat versions that really don't work.
