REP is known for creating high-quality fitness equipment designed by lifters, for lifters, and we hold our supplements to the same high standards. REP® Purist™ protein powder is packed with high-quality whey protein without all the other junk you don’t need. No artificial ingredients (like the other guys). No weird stuff you've never heard of (like the other guys). Always Informed Sport Certified and third-party lab-tested on every batch to ensure the quality, safety, and accuracy standards of world-class athletes. That means you can trust every sip meets the highest food safety standards — so it’s good for you and your performance. The scientifically proven benefits of high-quality protein powder like Purist™ protein include supporting muscle growth, recovery, and overall health by maintaining muscle mass, aiding repair, promoting a healthy weight, and strengthening the immune system.

We made Purist™ protein because as lifters ourselves, we were sick of all the gross, low-quality options endorsed by big-name athletes. They slap “high quality” on the label, but the ingredients tell a different story. Maybe they think lifters can’t read, or they’re hoping we're too lazy to check. Either way, you shouldn’t have to eat artificial, weird stuff just to get your protein in. Purist™ protein is just the good stuff—a healthy, better option. Our focus is simple: purity and quality that tastes incredible and is actually good for you. Purist™ protein powder is crafted with only four ingredients. Each serving delivers 25g of whey protein isolate sourced in the USA, with just 1g of fat and 1g of carbs – and a complete essential amino acid profile. In fact, 83% of the calories in our powder come from protein, so you know you’re getting the most out of every drink. Building muscle and recovering has never been so healthy and delicious.​
