By far the best Hydrolyzed Protein out there ( and I have tried a lot ). It mixes incredibly easily, even with a spoon and the taste is delicious, even with water. More expensive than other competitors but you pay for what you get, and with this, you get the best big time. I wouldn't choose anything else when it comes to Hydrolyzed Whey Protein. Been my stable pre/post work-out protein before it even started winning Hydrolyzed Protein of the year and now it's been 4 years in a row, I am not surprised.

YES! Tried all of the radical flavors for the Iso100. Mixes great, most likely on BOGO, and flavor shines well with Fairlife.
