Rice Oligodextrin question

Just got my first order yesterday and was wondering the following:

1- Can this be used for pre-workout?
2- Post Workout?

I am in MMA training. I am looking to cut weight and maintain lean muscle and maximize endurance training.

Thanks.

imo its great for both, it's what i use most of the time..with a low to medium gi rating i think it's ideal for someone cutting weight and retaining lean mass
