Out of stock



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. With Serious Mass™ – Vanilla, you’ve got nothing to lose and lots to gain. We’ve consolidated 1250 calories, 50 grams of protein, 252 grams of carbohydrates, vitamins & minerals, glutamine and creatine into every serving. It’s time to stop thinking small; get serious – Serious Mass™.
