Rule 1 (One) Isolate

By using super-pure 100% whey isolate and fast-acting whey hydrolysate, while completely omitting the use of whey concentrates, creamers, gums, and other fillers, we’re left with an industry leading Protein Purity Percentage (PPP) of up to 87%*. Gram for gram, R1 Protein has more fast-acting whey protein per unit of volume…period.

This protein formula is as pure as it gets. With 25g of protein and over 6g of BCAAs — entirely from intact and hydrolyzed whey protein isolates — R1 Protein helps support the recovery and growth aspirations of the most ardant muscle builders.
