I will tell you this, using this stuff will give you "some" symtoms of being diabetic thats for sure...it screwed up my thyroid a little, and took me a week to detox from it, i couldnt see 10ft in front of me for 3 days, and slept like there was no tomarrow..But to be honest i was on it for over 1 year straight with no breaks, but my doses were very low...hydroxycut/xanadrine@ 2 tabs a day ED, never would go over 4 tabs a day which is half recommended dose....my appitite still sucks, dont feel like eating much and its been over 2 mon since detox...also this product releases small doses of seritonin......not good long term friend..be careful
