Rule 1 Protein’s Flagship Premium Protein
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.
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 ardent muscle builders.*
Our Flagship Protein
Our fast-acting combination of whey isolate and hydrolyzed whey isolate (and virtually nothing else) supports muscle repair and recovery.*
