Serious weight gain requires serious calories. However, those who need the extra calories most often have the toughest time consuming enough of them. For many aspiring to be bigger, a highly active metabolism, weaker appetite and on-the-run lifestyle can make it a real challenge to consume enough calories through whole foods alone. Serious Mass is the ultimate in weight gain formulas.
With 1,262 calories per serving to boost daily calorie intake, 50 g high protein to support muscle growth and repair, over 248 g carbohydrates helping support muscle recovery , and now with 3g added Creatine to support performance per serving, you've got nothing to lose and lots to gain.
It is time to stop thinking small and get serious - SERIOUS MASS.
