Scientists have proven that if you’re not taking in enough total calories, you can’t build muscle no matter how hard you train. Bodybuilders have known for years that to get big you need to lift big and eat big! Guys looking to pack on mass need to eat around the clock. But many would-be massive guys have a busy lifestyle and aren’t able to cook tons of food and carry it with them wherever they go. Other guys simply can’t stomach the thought of eating pounds of food every two hours. If you’re already eating lots and you still simply cannot gain weight, MASSFUSION™is for you!
