I got to test the Acai Ultra for free, but many thanks. I've taken without great expectations and ca noticed after 5 days that I'm not as tired and exhausted. That was always better in the next few days, I am much more powerful. I have not taken off, it would have to probably change the diet. The Tapletten are somewhat large, whoever is struggling with swallowing should they share. So who buys to boost performance, I can recommend it only. One point deduction for the size and no weight loss.
