Serious Mass tastes rich and sweet but it must be expected. With a great number of carbs, proteins, and fats, it has to taste sweet. The chocolate flavor is not too intense and has the right amount of thickness. However, with a shakes bottle, this powder fails to blend well. You will find lumps. To avoid lumps, use a blender instead.
