Overview

Legion Whey+ provides 22g of protein from 100% grass-fed whey isolate (not a blend of concentrate and isolate). Founded by Mike Matthews (author of Bigger Leaner Stronger), Legion is built on the principle that every product should be based on published scientific research. Whey+ uses no artificial sweeteners, flavors, or colors — sweetened with stevia and erythritol. The grass-fed whey isolate provides a cleaner amino acid profile with higher CLA and omega-3 content compared to conventional whey. Each batch is third-party tested for purity and potency.
