Both BPI Sports ISO HD and Cellucor COR-Performance Whey are designed to fuel fitness enthusiasts with 25g of protein per serving, focusing on lean muscle development and recovery. While BPI Sports ISO HD offers a pure whey isolate protein, Cellucor's product blends whey isolate with whey concentrate, adding digestive enzymes to aid absorption. BPI's product impresses with its lean ingredient list, but Cellucor's blend and added enzymes make it a bit more versatile.
We recommend Cellucor COR-Performance Whey as the superior product. It not only offers a blend of whey isolate and concentrate but also includes enzymes like protease and lactase to aid digestion. The taste and texture is also great, and it's positioned as a mid-range option that provides great value. While BPI Sports ISO HD is a commendable product, Cellucor's blend and thoughtful additions give it an edge in supporting various fitness goals.
