hi, can anyone tell me how exactly to use them? i know whey protein should be used after workout for anabolism. I currently have ProMatrix 7 Whey Protein and Creatine Monohydrate. I haven't taken the Creatine yet since the trainer in my Gym doesn't seems to know what he's selling. So it is safe to take both protein and creatine? if so how do i take them? both before and after workout?
