We make it simple by providing full label disclosure. We never hide ingredients in deceptive proprietary blends. Our labels are simple, honest and disclose every single ingredient along with the exact dosage. Our label doesn't state "100% Whey", it states specifically "100% Whey Protein Isolate" so our unflavored version contains absolutely nothing but whey protein ISOLATE, and our flavored versions contain a small amount of flavoring, that's it.
