Optimum Nutrition Gold Standard 100% Whey Protein Powder - Double Rich Chocolate Flavor (1 lb) | Muscle Recovery & Post-Workout Supplement for Athletes & Fitness Enthusiasts

I have been using this brand of whey for a decade. My opinion is that it is the best on the market. Low sugar, high fiber, high protein, and mixes well. I repeat, it mixes well! There are many flavors to choose from, so when you start to get tired of one you can switch to another. I have yet to try a flavor and hate it, although some flavors are better than others. My favorite is double rich chocolate and my least favorite has been strawberry banana. The price is also competitive to other brands. I typically buy the 5 lbs. tub as this is really how you start to save.
