It is time to stop thinking small and get serious – SERIOUS MASS®

Great flavor, easy to mix. I wouldn’t change it for a different one.

Best protein powder for bulking and getting stronger.

As it says in the back, with serious mass there's nothing to lose and a lot to gain, the product lives up to its name, it has helped me and my friend put on some weight used with workouts, we both have fast metabolisms and it helps us get the calories we need for growth, it tastes delicious, I usually use it before going to sleep after the gym I would recommend it 💯, thank you serious mass.
