How does ON compare to Now Whey Isolate ? I would think Now Whey Isolate is much pure when compared to ON whey.
I just took a quick glance at it, and it looks to be a more pure form of whey. It doesn't have any sucralose, aspartame, or added sugars. With that said, I wouldn't expect it to taste near as good as ON, and you may even have to mix with something other than water to make it taste good enough to drink repeatedly. Just guessing though. I've never tried the NOW brand.
