If you’re looking for a high-calorie, nutrient-dense mass weight gainer, Optimum Nutrition’s Serious Mass may be a good choice for you. This supplement contains 1,250 calories per serving with 50 grams of protein, 252 to 254 grams of carbs, and less than 5 grams of fat in four flavors: Chocolate, Chocolate Peanut Butter, Strawberry, and Vanilla. Additionally, there are 3 grams of creatine monohydrate, which effectively supports lean muscle growth.
This weight gainer does contain artificial ingredients including sucralose, which may matter to some people. While users appreciate the taste, Serious Mass has 9 grams of added sugar for a total of 20 grams per serving which may be a dealbreaker for some. However, Serious Mass powder is packed with 25 essential vitamins and essential minerals offering micronutrients not always seen in weight gainers.
This product mixes best with cold water or in a blender. While most users find the mixability acceptable, it does leave some lumps if not mixed in a blender. Mix this powder with some added fruit, peanut butter, or supplement of your choice or take it in solo for a serious dose of extra calories.
