Fuel your body's engine.

Times are tough and have required many personal sacrifices, but your active lifestyle doesn’t have to be one of them. Protein is an essential nutrient to drive strength, fitness and physique. But not all proteins are the same. Progenex SUSTA!N is the most effective, efficient and clean whey protein isolate available. The sort of quality you expect from Progenex.

Quality, Clean & Complete Protein

Progenex SUSTA!N uses a proprietary cross-flow, microfiltered whey protein isolate, where sweet dairy whey is gently filtered and concentrated without the use of chemicals. This yields a high level of undenatured whey protein, which is virtually lactose-free. The process leaves valuable bioactive components intact and creates a superior-quality whey protein isolate.
