I have not taken it personally but I found a lot of good information about it on this
NuPhedrine website:
http://www.nuphedrine.info
Apparently it has Hoodia Gordonii & some other ingredient that's supposed to be like ephedra. I know a lot of products now are using Hoodia, so it's probably working for people. I don't know about the other ingredient but if it's like ephedra then it should help you burn calories. I used to use ephedra and it was awesome.
The customer before & after pictures look pretty good... probably worth a try if you're desperately looking to lose some weight. Hoodia will probably help with the will-power to curb snacking.
Good luck!
