I have used C4 before, with strong effect I might add, never really used creatine. I was wondering since C4 already has some creatine in it, is it ok to use them at the same time and will it possibly change the effects of each other.
I have used C4 quite a bit along side with Creatine as well. Depending on your creatine, C4 won't be giving you that much creatine (I believe it was 1g per scoop). Some people claimed creatine needed a "loading phase" but that hasn't been proven.
In fact, the "loading phase" was popularized by companies who wanted to sell more of their product. They would suggest a loading phase and the consumer would be using more during the first weeks (without any added results).
Creatine is a natural amino acid present in the body of humans and animals. The human body has 100-115 grams of creatine in the form of creatine phosphate. No negative side effects have been noted in the research with the recommended levels of supplementation.
Depending on your weight, here are the creatine intakes per day:

You'll be fine if you use creatine and C4 together. Just drink water due to the added creatine levels. When I cycle on creatine I use about 5g per day even if I'm 170lbs.
P.S: If you liked C4, you might love Craze. My new pre-workout.
I have no idea what C4 you are talking about, but if it includes creatine, the effect of adding more creatine, will be the same as if you just took lots of creatine.
Check how much creatine is in C4, then add creatine up to a max of 5g per day. More than that may cause minor negative effects, but is mostly a waste of money. Consuming more than 5g a day of creatine has no research-backed positive benefits.
