Why do you need Carbs do Build Muscle? (srs)

[lee__d]

How do you know how much protein to eat before a workout, lets say you get protein from whey powder, how much would be ideal for a shake. Theres about 24 grams in a scoop I heard you can only ingest about 10 grams an hour.

Your body will eventually digest all protein in most cases ( I mean if you use some ridiculous example of trying to eat 500g pro at once, you may end up puking or excreting some).

The average male your age will have enough with 25 gram protein.

As far as for muscle protein synthesis, yea this would probably be fine.

That said, paying attention to the total amount of protein you need (while, preferable getting some around your workout) is far more important.

Yeah your body can digest a lot more than ±40 grams of protein per meal but your muscles just won't be able to use it.
