This is my peri-workout setup as well. I've been playing around with different combinations:
1. 1 scoop of each prior, during and after
2. 1.5 scoops Surge Workout Fuel prior, 1.5 of both during, and 1.5 MAG-10 after
3. 3 scoops Surge Workout Fuel prior, 1 scoop MAG-10 during, 1 scoop MAG-10 after
I'm still not sure what I like the best just yet, but I'm leaning towards #2
How do other people work out their peri-workout servings?
