I bought xenadrine and it was the worst thing ever! It was so confusing! The box said it was xenadrine rfa but the instructions were specifically for xenadrine rfa 1. Then I called the help number and was told that my barcode was for cytodyne xenadrine. After conferring with my doctor he said that I wanted xenadrine ephedra, but not xenadrine nrg! Why is this so confusing? Is it all the same stuff? I want to buy xenadrine because it sounds like a good idea, but I’m afraid to spend money when I go to buy xenadrine rfa and have it be the wrong stuff! The xenadrine diet might be good but if no one is smart enough to know how to use it correctly then I don’t know if it’s worth my money.
