Clean Gainer

High Calorie Mass Gainer[short] R1 LBS High-Calorie Weight Gain Formula The premise for R1 LBS is a simple one: to be BIG, you need to go BIG. With over 1,000 calories, a 200-gram complex carb blend, and 40 grams of protein from three types of whey, R1 LBS is large and in charge. In addition to a 5:1 carb to protein ratio, this calorie-packed formula provides added creatine, MCTs, and glutamine to help you achieve your most SIZEable aspirations. Transparent Formula ZERO Creamers ZERO Spiking ZERO Soy Protein R1 LBS BETTER INPUTS High-Calorie Weight Gain Formula Over 1,000 calories! * 40 g all-whey protein * 200+ g complex carb blend with organic rice bran and Carb 1™ * 2 g creatine monohydrate * 1 g medium chain triglycerides (MCT) * L-glutamine fortified Carefully blended and packaged in a GMP facility in the USA * Per Serving Select Flavor Chocolate Fudge Vanilla Creme Strawberries & Creme Cookies & Creme Chocolate Peanut Butter Directions Tasty Shakes: Mix two (2) scoops of R1 LBS™ with approx. 18-20 oz. of water, milk or your favorite beverage in a shaker cup or glass with a spoon.

What is the difference between a weight gainer and a lean gainer? Weight gainers are designed for maximum size. Lean gainers contain fewer calories, but provide as much or more protein as weight gainers. Weight gainers are suggested for "hardgainers" with smaller appetites and/or faster metabolisms. Lean gainers tend to be used by athletes that already have a good base and are looking to add size more gradually. Pound for pound, lean gainers are more expensive than weight gainers. What is the best way to use R1 LBS? R1 LBS should be combined with a high-calorie diet and exercise. Do not use R1 LBS in place of meals; add R1 LBS to the food you normally eat for extra calories to help pack on mass. How does R1 LBS differ from R1 Gain? R1 LBS is a higher calorie (1000 kcal, 40 g protein) weight gainer. R1 Gain is a higher protein (50 g, 530 kcal) lean gainer.

Sustainability Score

62%

Rule One demonstrates mixed performance in sustainability practices. While they use recyclable packaging and have implemented some energy-efficient manufacturing processes, their transparency regarding supply chain and environmental impact is limited. They have basic animal welfare standards but lack comprehensive third-party certifications. Their labor practices meet industry standards, but detailed ESG reporting is minimal. The company shows potential for improvement but needs stronger commitment to sustainability initiatives and better public disclosure of their practices.
