The Science of Size: How Mass Gainers Work and Who Should Use Them
Briefly

Mass gainers are nutritional supplements designed to facilitate calorie intake, enabling individuals, especially those with fast metabolisms, to increase their body mass effectively.
The primary goal of a mass gainer is to supply the body with essential nutrients that promote muscle growth and weight gain, crucial for those struggling with regular intake.
Mass gainers often contain high-quality proteins like whey and casein, which ensure rapid absorption for muscle recovery post-exercise, vital for growth and repair.
Incorporating carbohydrates, mass gainers become a significant energy source that fuels workouts and daily activities, helping bodybuilders and fitness enthusiasts in their regimes.
