How does a mass gainer differ from a protein shake?

A protein shake mainly contains protein (20-50 g) with few carbohydrates (under 10 g), providing 100-200 kcal. A mass gainer contains both protein and large amounts of carbohydrates (50-250 g), providing 500-1,500 kcal. Choose a protein shake if you want protein without extra calories, and a mass gainer if you need a caloric surplus for mass building.

Will a mass gainer make me fat?

A mass gainer alone will not make you fat — weight change depends on total daily caloric intake and training. When consuming a mass gainer with regular strength training and a moderate caloric surplus, most extra energy goes toward building muscle. Without training or with too large a surplus, body fat may increase.

When is the best time to drink a mass gainer?

The best times are in the morning (energy stores are low after sleep) and immediately after training (muscles need protein and carbohydrates for recovery). Some athletes also drink a mass gainer before bed to ensure a continuous flow of amino acids to muscles overnight. Spreading intake evenly throughout the day is important.

How do I choose the right mass gainer?

Look at the protein-to-carbohydrate ratio — quality mass gainers contain at least 30% protein and use complex carbohydrate sources (oats, buckwheat, sweet potato) rather than just maltodextrin. Also check sugar and additive content. Hardgainers benefit from the highest-calorie variants, while others may prefer a more moderate option.
