I use ON Serious Mass bought from Amazon If you are a skinny guy like me and want to gain muscle and weight, then you may need a mass gainer. Mass gainers are bodybuilding supplements which contain more calories than normal protein supplements. They contain larger amounts of carbohydrates and fats to boost your calorie intake. When you daily calorie intake is more than your calorie burn, that is when you start to gain weight. Usually you gain the calories from whole foods. But there is a limit to how much you can eat. If you are like me, then that means no matter how much you eat, you are unable to gain weight. People who can't gain weight easily are called hardgainers. If you eat enough, then there are 2 reasons for not gaining weight: 1) You have a fast body metabolism which means that you burn calories at a tremendous rate. 2) You can't eat much and get only enough calories for carrying out your day-to-day activities.
