First off, I am an avid gym goer. I don't like drinking regular protein powders. They are all way too sweet and have a funky after taste. I have tried other "clear" protein products (Protein2O, Gatorade) before but they would never mix very well (clumpy) and be very chalky feeling in my mouth. I was really reluctant to try this. This is the best clear protein product I have tried. I haven't had a chance to try the other flavors, but the Mango Clementine is really good!
