I thought creatine had to be first absorbed by the kidneys to be then put in the muscles? If so slin wouldnt have an effect? Right or wrong?
The kidneys are relevant with creatine but no matter how it's absorbed (intestines) the insulin plays a part in transporting the creatine from the blood stream into the muscle.
My original point in posting in this thread was that you don't need exogenous insulin to accomplish that. If you take just 5 grams of creatine the serum concentration of creatine in your body will go up about +6X what it was prior to supplementing, assuming you didn't just eat.
If you're already going to take insulin, then using creatine with it isn't a bad idea... But don't take insulin just because you think it'll make creatine more effective. (Not directed at you, trukk... Just a general statement because it seemed like that was the idea behind the thread)
