Protein?

[Praetorian]

Last note I would also avoid creatine for atleast a week prior to MEP's and/or while in service. Not only can creatine dehydrate you as Ranger Rangertom pointed out but It will also show up in your urine test and can be a red flag, it was for me when I went through the process of gaining a Top Secret clearance. They just asked me why my creatine levels were so high, not sure exactly 100% why but still questioned.
