Serious Mass is a high calorie weight gainer which should be used only by someone seeking rapid weight gains. The high ratio of carbohydrates means that it supplies a lot of energy but that comes with the caveat that if you do not train frequently it will not be a good choice for you. On the other hand for people performing a lot of cardio or with superfast metabolisms, Serious Mass supplies calories in an easily digestible form to make weight gain easy.


Serious Mass should be reserved for phases where you are trying to gain weight quickly and are happy to accept a modicum of fat gain. Outside of bulking phases those who perform high amounts of cardiovascular activity (which depletes carbohydrates more than weight training) will find this a good post-workout choice.


Serious Mass is a gainer which should be used with caution if you are seeking lean mass gains as the overwhelming number of calories and carbs means that unless you are naturally very skinny you may end up gaining too much fat. On the other hand for the kind of person who claims they can never gain weight no matter how much they eat, Serious Mass will be perfect.
