I've been buying my protein powder from Costco from the past year, and it's more or less a no-name brand, it says "Whey-Isolate" and comes in Plain/Chocolate/Vanilla. There are 110 Calories, 35g of protein, and 1g of Carbs per scoop. My question is this powder any different from the big brand names, and how would there be a difference in quality besides taste? Furthermore, does anyone have any experience with "Muscle Milk" products?
