I tried 100% Hoodia and it has worked for me! (And with no side effects!) Check with your doctor before starting any weight loss program. The problem w/Hoodia is 90%+ are scams. The real Hoodia is expensive and only the one imported from S.Africa has been shown to work. Many people go for the low cost scam Hoodia and have no results! I lost quite a bit of weight and once in awhile I take it for a couple of days if I start to gain a few pounds. I did my original research here a very long time ago: http://www.hoodia-diets.info/hoodia-diet-capsules.htm http://www.hoodia-diets.info/hoodia-gordonii-diet-use.htm http://www.hoodia-diets.info
