Well, they were checking results of When protein is a very, very tough, and long process. You have to gather certain bodybuilders, fix their diets, maintain their exercise schedule, and give them scoops of whey protein at the right intervals. We included 20 people, out of which 6 were female bodybuilders. The testing process went on for 40 days, and the results were tremendous. That's why, instead of writing about the best whey proteins, we've concentrated only on Asitis proteins and other supplements. The whey protein isolate of Asitis brought the best results. So, the answer is, YES, it does work, but only if you are taking the right diet and following a perfect exercise and sleep schedule.
