Purist® Whey Protein Powder

NO GIMMICKS. NO NONSENSE. BACKED BY SCIENCE. POWERED BY ONLY FOUR INGREDIENTS.

REP is known for creating high-quality fitness equipment designed by lifters, for lifters, and we hold our nutrition products 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 recovery, and overall health by 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. Fueling your body has never been so healthy and delicious.

No artificial anything: Zero artificial sweeteners, colors, flavors, fillers, or gums.
LOW CAL: 120 calories for chocolate and 110 for vanilla.
NO SUGAR: A clean choice for health-conscious athletes.
Isolate whey protein powder: Highly refined, easily digestible, lean whey isolate has a higher protein content, lower lactose, and less fat and carbs than whey concentrate.

Happy taste buds: Available in Vanilla Bean and Dutch Chocolate for the tastiest shakes and more. It’s easy to mix and incorporate into various recipes.
Ingredients: Made with only four ingredients that are actually food — not a science experiment.
Soy free: A clean, allergen-friendly option for those with dietary sensitivities.
Environmentally conscious: Comes in eco-friendly gusseted bags, which are far more sustainable than conventional plastic tubs.
