Although the price is more expensive then most whey proteins on the market, Optimum Nutrition's 100 % whey has always been my go to protein source. I usually stick with buying the chocolate flavored mixes since the taste of them are bar to none the best on the market. Whether you mix the whey with water or milk you can not deny it tastes great which is nice to have with a whey protein (especially when cutting weight). The mixibility is instant and you do not need to spend minutes shaking your bottle to get rid of the clumps like most protein powders, it's also very smooth not heavy & thick. The amino acid profile is great for recovery, fat loss & muscle gain. I definitely recommend this product to anyone who hates the taste of cheap whey. ON 100% Whey has always been & always will be the best whey protein on the market.
