Protein Before or After Workout

Whenever you want to it's not going to make a difference

You'll see a lot of talk by folks that lift that you want to have a good amount of protein in you before a workout, then slam a shake post workout with some good "fast acting" protein.

The reality is that your body is digesting nutrients all damn day. Folks who build a high amount of lean mass are doing so effectively not because they are taking a protein shake at the magical timeframe before or after training, but because they are steadily ingesting protein in high amounts period.

Honestly the best pre-workout (aside from some supplements out there like Assault) is something like grapefruit and black coffee. Carbs = energy, and caffeine is a basic stimulent.
