I really love that whey. It has, by far, the best flavor among all I've tasted. It dissolves quickly with both water and milk. If you mix it with milk and beat it in the blender, neither does it look like you're taking a protein supplement, but rather a milk shake. On the days when I'm in a hurry, I manually mix the whey in the bottle with water and the taste is good too. A friend said that whey blended with almond milk is also a good request. Also, I use this whey to cook pancakes, muffins, waffer and other recipes that include extra protein. I'm a chocoholic, so I always end up buying the chocolate flavor. But I recently bought the one of cookies to try and it turned my favorite flavor. The whey-flavored cookies have bits of chocolate chip cookie mixed with the powder, so it is very tasty. Regarding the formula, a scoop has 24 grams of protein and very little carbohydrate, which is excellent. I've noticed that the ON whey has a smaller scoop size than most powders, which means you can put more in one drink and still it mixes easily. I take the whey soon after my workout and it helps with the pain the next day. I recover from my workouts faster and can re-train before, so I see a bigger result using whey. I also take the whey from ON when I am on a busy day and do not have time to arrange a snack. And most important of all: it works. I've seen a lot of growth since I started taking it. It helps control the craving for sweet eating and if used along with a good diet and exercise will definitely help you increase your muscles. I also recommend this product if you are lactose intolerant. My cousin is lactose intolerant and tried several whey proteins but they always irritated her stomach and intestine, since that whey told me she can take before and after workouts and has no side effects. I can not think of any disadvantages to whey powder from Optimun Nutrition. The price for me also seems very reasonable considering its quality. I am very happy with my purchase and will probably continue to buy more.
