I was able to test the Acai Ultra 20,000 and am very happy with the product. After just over 3 weeks I could tell that I felt fitter and more flexible. I managed to even more in everyday life. I had my diet also changed a bit and could thereby lose weight 2 kilos and thus the Acai Ultra really seems to act as food. Also had colds than any other in my family and friends I am still verschon nd that I owe probably only the Acai Ultra. I'll take it repays on. For me it's a product that's perfect for me. Can not recommend it more!
