I'm familiar with two versions of MAG-10. One with a dosing of 6 caps at a time, the other with a dosing of 5 caps at a time. It sounds like you have the 6 caps at a time version right?
Anyway, not sure how to suggest using it. I'd say that the more you are using per day the more important it becomes not to be wasting your effort.
Is there anything in your planned two week periods that might interfere with your trips to the gym or your ability to eat enough of the right foods?
As a final thought, when I've taken one dose split over a day, I'd split it unevenly. After a workout and for the following dose I'd take four, followed by doses of two until the next workout. Whether or not it made any difference I'll never know.
