Imported product of great quality. I have used other national brands but I did not get as good a result as whey optimum. The flavor cookies is tasty, do not get as sick as others, since I use daily. Very simple preparation, I carry in the bag, and in the run of the shifts it also serves as a practical snack and helps not to catabolize, since the most difficult at the moment is to maintain a regular diet and to maintain the gains obtained in the bodybuilding. great store, great antedimento, whenever I had doubts got store response, fast delivery and totally safe! It delivers easy and offers excellent muscle recovery, quality imported whey unfortunately is light years of national, worth values are high due to the dollar.
