Eating protein after working out only increases the building of connective tissue in muscles for about 4 hours - after that, the building rate goes back to normal.

Eating a big protein meal (100g) after working out makes your muscles keep building for longer than a smaller meal (25g), at least for 12 hours.

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 how fast your muscles break down protein - it just helps build more muscle without affecting the breakdown process.

When you eat a big protein meal (100g) after working out, your muscles absorb more of that protein for building than when you eat a smaller meal (25g) - about 13% of the big meal gets used for muscle building.
