Quick Summary
Optimum Nutrition Serious Mass is a chocolate peanut butter mass gainer powder with 8 servings in a 2.73 kg pack. It is described as a high calorie formula with vitamins, creatine and glutamine, and the pack size matters because this is a limited-serving product rather than a large bulk tub.
For buyers, the key checks are the flavour, serving count and pack weight, plus whether the preparation method suits the way you want to use it. The product also appears in multiple flavours, so the selected flavour is an important part of choosing the right version.
