R1 Protein Whey Isolate is made with super-pure whey isolate, fast-acting partially hydrolyzed whey isolate, and virtually nothing else. This elite formula completely omits the use of whey protein concentrates, creamers, amino spiking, banned substances, and other things that dilute what you really came for – protein. Even better, it tastes great too.
