When I was cutting I was doing a pre workout drink, BCAA during workout and a protein shake immediately after workout. If the workout called for steady cardio (not high intensity interval), the shake would come before the cardio.
I don't take pre-workout or BCAA when I'm not cutting, protein shakes only followed by a meal with complex carbs/fats/protein.
I also try to take in carbs one hour before the workout.

I only started taking pre-workout drinks, cause on a low carb diet I couldn't last a whole workout.
