    ACCELERATED GAINS – With over 1,220 calories, more than 250g carbohydrates, and 40g protein from three types of whey, R1 Mass Gainer puts you in charge of transforming to XXL.
    6:1 CARB-TO-PROTEIN RATIO – The 6:1 carb-to-protein ratio in this calorie-packed formula can help you pack on desired pounds.
    QUALITY CALORIES – Our formula also includes 9g naturally-occurring BCAAs, creatine, MCTs, and glutamine. We intentionally left out: creamers, soy protein, and banned substances.
    HOW TO USE IT – R1 Mass Gainer should be combined with a high-calorie diet and weight training or other high-intensity exercise. Use it in conjunction with the food you normally eat for additional daily calories. Do not use in place of meals.
    BETTER INPUT, BETTER OUTPUT – You’ll see these words all over our products. It means we’re relentlessly pursuing better input to ensure we never put a product on our site—or on a shelf—that we wouldn’t put in our own gym bag.
