Scientists at Nova Southeastern University in Florida rounded up 19 lifters and split them into two groups. Both groups did the same workout five days a week for 4 weeks. One group took 5 grams of creatine before their workout and one group took 5 grams of creatine after their workout.
After 4 weeks, the men in the after-workout creatine group gained TWICE as much lean body mass as the pre-workout creatine group. The after-workout group also lost about 2.2 pounds more fat than the pre-workout group, in addition to being able to bench a couple of pounds more than the pre-workout group.
