ISO HD™ is pure, clean, muscle-building fuel. Each scoop of BPI ISO HD – 5 lb delivers 25g of 100% whey protein isolates with only 4g of carbs and 1g of sugar. Isolates are filtered to remove most of the lactose, fat, and carbs. This results in an end product that is higher in protein, leaner and digests faster than standard whey protein. But we take an extra step to ensure that you only receive the highest-quality protein. Each of our protein bottles is inspected by a third-party lab to guarantee that what’s on the label is actually what’s in the bottle. Use this formula with confidence to support muscle-building and/or weight loss programs
