12 hours

The 12 Hour Rule applies to any sporting event where the male athlete(s) jack off exactly 12 hours before their competition. It is proven to raise testosterone levels and enhance performance for any sport. It is important to not mastrubate too close to your competition, as this will not allow for enough time for your body to restore its testosterone supply. Too early, however, and it will have no effect on your performance. It is not yet proven if this works on females yet. If anybody would like to test and contribute, be my guest.
