Rule1 R1 Whey Protein Isolate 5lbs

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.

Our Flagship Protein.
Our fast-acting combination of whey isolate and hydrolyzed whey isolate (and virtually nothing else) supports muscle repair and recovery.

As Pure as it Gets.
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.
