Best way is to take it in the morning or 30 mins before workout, it has long active life, so you don't need to split the doses. How much fat you can lose I cannot know but it changes body's energy source from carbs to fat even when resting you lose fat. It increases cardio, even weight lifting feels like cardio because body doesn't use glycogen so it has no explosive power bench press feels like cardio, squat feels like cardio. You don't need regular rest between sets because muscles don't burn and heart capacity is much better than normal, in 10-15 seconds you recover so you go on working out. Also I would do sprint for an hour at the end of my workouts, to get runner's high, when on cardarine I stopped doing it because sprint didn't give me any high and it was like regular walking.
