## Description

More calories. More protein. More carbs. SERIOUS MASS by Optimum Nutrition serves over 1,200 calories, 50g of blended protein, and over 249g of carbohydrates per 2-scoop serving to help you maximize your daily caloric intake – the ideal post-workout and between meals shake for sizing up your goals. SERIOUS MASS provides you with more tools to help you pack on pounds, when taken in addition to normal calorie intake and over time with regular resistance training.

Review: It helps a lot - Optimum Nutrition Serious Mass is a great choice for anyone looking to gain weight, build muscle, or increase overall calorie intake. The Chocolate flavor mixes smoothly—especially if you use a blender—and has a rich, dessert-like taste without being overly sweet. Each serving delivers a very high amount of calories, protein, and carbs, which makes it ideal for people with fast metabolisms or those who struggle to eat enough throughout the day. It also includes added vitamins, minerals, and creatine for extra support. The bag is large and lasts a good amount of time depending on how much you use. The powder is heavy, so mixing by hand can be a bit difficult, but blending solves that problem easily. Overall, Serious Mass is effective for healthy weight gain and muscle-building goals. If you need a calorie boost and don’t mind a thick shake, it’s a solid and reliable product.
Review: Great weight gainer - Great product for the money. It mixed well it's loaded with calories and carbs. Tastes great. It did what it was designed to do so if your looking to add some lbs on the scale this will work just fine.

Great product for the money. It mixed well it's loaded with calories and carbs. Tastes great. It did what it was designed to do so if your looking to add some lbs on the scale this will work just fine.

### ⭐⭐⭐⭐⭐ Quality mass gainer
*by C***S on December 24, 2025*

Optimum Nutrition has consistently produced some of the highest quality whey products I've used. Easier to stomach and better tasting than competitors. Dissolves well in water as well as milk when mixed properly. I've used the product for years and it has served as an effective compliment to my workout regimen.
