MUTANT MASS was developed over 2 years of research and is based on sound, proven science. More importantly though, the finished MUTANT MASS formula was also tested in the gym, where it was put through its paces by real life bodybuilders and strength athletes. The results? If you add just 1 serving of MUTANT MASS per day to your routine, you can add up to 5lbs of fat free muscle in just the next 14 days, increase your bench press by 10-20lbs and boost your chest size by 2.5 centimeters (1″). That’s not rocket science – that’s just MUTANT MASS doing its’ amazing job.
