i have tired many different types of hoodia including gordonii you can buy these online but some online stores are suspect so be extra careful.
i have personally had better results with hoodia+green teas so i highly reccommend it. i think you should try out green-tea hoodia.
another thing about buying hoodia... you can save alot of money by using the free trial offers offered by most vendors (i only pay shipping)

take care :)

I read a label for hoodia stuff...it said "for best results, exercise regularly and follow a healthy diet" or something like that...
If you're gonna exercise and eat well..u don't need the hoodia...in my opinion, they're a scam.

No diet pills work in my opinion...I finally tried "Whole Body Cleanse" and the results were astounding!!! I cleansed for 2 weeks and 2 weeks later, I noticed I shed weight. After 2 months...I dropped 2 dress sizes...and the only thing I did was "walking". I also chose not to put the bad food back in my body (which will work for anyone, I think). Also, if you try it I would recommend "juicing" as well. Whole Body Cleanse can be found at any natural food store..and costs about $25 in USA.
