How much protein do I need to build muscle?

Research points to roughly 0.7 to 1g of protein per pound of bodyweight per day, spread across three or four meals, to maximize muscle growth alongside resistance training.

Do I need a mass gainer?

Only if you struggle to eat enough. Mass gainers pack several hundred calories per serving from carbs and protein, which helps hard gainers reach a surplus. If you already eat plenty, a standard whey plus food is usually enough.

Whey or casein for muscle gain?

Both work. Whey digests fast and is ideal right after training, while casein digests slowly and is a popular choice before bed to supply amino acids overnight. Many lifters use both.

When should I take protein to build muscle?

Total daily protein matters most, but many lifters have a shake within an hour or two of training for convenience. Spreading protein evenly across the day supports muscle repair.
