I have researched countless hours and there are always as many bad reviews as good ones. Everyone on this site says "research" but its point less. I eventually tried a site recomended by second hand info. The stuff causes so much pip its unbearable. After 2 weeks started seeing blood in my urine. WTF!!! It didn't use to be this hard to get legit info. Did 7 year bid and man has the game changed.
