Rule 1 Mass Gainer - High-Calorie Weight Gain Formula with 1,220+ Calories, 250g+ Complex Carb Blend, 40g All-Whey Protein Per Serving (8 Servings, Chocolate Peanut Butter)
- 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.
