Protos Iso isn't just protein, it's the purest expression of muscle-building fuel. We harness the power of Whey Protein Isolate (WPI), the gold standard for bioavailable protein, to unlock your fastest gains yet. Protos Iso also contains a superior form of chromium picolinate from Chromax® to help increase the body’s storage of ingested carbs as glycogen instead of body fat as well as boost protein bioavailability.
