Eating more protein after working out makes your whole body build more protein - the more protein you eat, the more protein your whole body builds.

Eating protein after working out doesn't change most amino acid levels in your muscles - only the branched-chain amino acids like leucine increase with bigger protein meals.

Eating protein after working out doesn't change most amino acid levels in your muscles, but it does increase the levels of branched-chain amino acids like leucine, especially with bigger protein meals.

When you eat a big protein meal (100g) after working out, your body releases more protein building blocks into your blood than when you eat a smaller meal (25g) - about 53g vs 16g over 12 hours.
