Sports supplements come and go, promising to be the magic bullet that will suddenly turn us all into supermen, but one by one their claims are disproven and they are forgotten, only to be replaced by new and more exciting promises.

If any single sports supplement out there can be said to work, than its Creatine, which leads us to the question: should you take it when about to undergo Insanity or P90X?
