INTRODUCING RULE 1 MASS GAINER
The premise for Rule 1 MASS GAINER™ is simple: to be more massive, you need to go more massive. MASS GAINER™ builds upon R1 LBS’s strong foundation with added calories and a more substantial complex carb blend to help fuel tougher workouts, bigger gains, and greater muscle recovery.*
BIGGER & BETTER.
MASS GAINER™ is XXL and in charge. Each calorie packed serving supplies a 6:1 carb to protein ratio plus naturally occurring BCAAs and added creatine to help fuel your workouts and add size quickly.*
- Over 1,220 Calories (1,500 calories mixed with low fat milk) to help your customers pack mass on fast.*
- 250g+ Complex Carbohydrate Blend to fuel workouts and support glycogen resynthesis*
- 40g All-Whey Protein for high drinkability, easy digestion, and fast acting delivery.*
- 9g Naturally Occurring BCAAs to aid muscle recovery and rebuilding.*
- Just 6-8g Fat (< 2.5% of serving weight)*
