Query: Simple, quality protien and nothing more.

No artificial colors; flavoring; or sweetener (it does use a natral sweetener called stevia). I'm not a scientist so I can't coment on the whey formula its self, however I can say that I've been using it for a couple weeks now and I'm noticing results. I've been eating more vegetables lately and this whey has been a big source of my protien. Given this, I'd have to say it does the job it promises. As for the taste, I think its fine. Its not delicious, but certainly not gross or offensive like one reviewer has said. If you want a great whey protien with no additives and emplty callories then I'd recomend you give this a try.
