Serious weight gain requires serious calories. Ironically, those who need the extra calories most often have the toughest time consuming enough of them. For many aspiring to be bigger, highly active metabolisms, weaker appetites, and on-the-run lifestyles make consuming sufficient calories through whole foods alone a real challenge. With Optimum Nutrition Serious Mass, you've got nothing to lose and lots to gain. ON has consolidated over 1,250 calories, 50 grams of protein, over 250 grams of carbohydrates, and 25 vitamins and minerals, with added glutamine and creatine in every serving. It's time to stop thinking small; get Serious Mass.
