Hey I just bought some Optimum Nutrition Whey. I used to have Whey/Creatine powder, called Weight Gainer. Well now i have the 100% Optimum Nutrition Whey and I also bought some Power Creatine. is it ok if I take these two at the same time? I wont have them in the same drink so not mix them, but I mean in the same day, is it ok to take both things? Also I was reading about the Power Creatine how long should I be on it, I know its 5-7 days for the bulking stage but after that for the single serving a day is their point where i should stop taking it, like 2 months?
