No gimmicks! No sleight of hand! No games! Whey Shake’s™ singular protein source is pure, wholesome whey protein concentrate. Although it is commonplace to add a small amount of whey protein isolate or hydrolysate (whey peptides) into a formula in order to list them as ingredients on the label, we decided to march to the beat of a different drum when creating Whey Shake™. Instead of trying to trick our customers, we are gladly proclaiming that Whey Shake™ contains only whey protein concentrate. This level of truthfulness makes little sense if Whey Shake™ contained cheap, inferior denatured whey protein that tastes horrible, dissolves incompletely and metabolizes inefficiently. On the contrary, Whey Shake™ contains only Promina™ brand whey protein concentrate--the purest, healthiest, best tasting, most soluble and most undenatured U.S. manufactured whey protein concentrate available. As with all Syntrax® brand proteins, Whey Shake™ is not only theoretically superior, but also practically superior to other whey protein products on the market. Little benefit is achieved if a product does not offer real-world performance equivalent to the performance stated on paper. With Whey Shake™, we guarantee a product that will provide unmatched nutritional performance as well as taste delicious and mix instantly . . . all in the real world!
