I agree with the Optimum Nutrition %100 Whey-- great value. As well as ISS's version.
there are also a number of whey supplements that are the general protein plus vitamins-- considered MRPs (but an MRP for me has to have a lot or carbs in it). There are great gainers out there from ON and ISS that have low sugar. Bottom line, don't waste money on those 15 serving containers of name-brand proteins. It is just a supplement-- and unless you supplement your income, it will dig you a debt hole.
