when it says a 4oz. banana is that with or without the peel? also is cocoa powder ok to add in with my oatmeal?

thanks

without the peel--I believe.. thats how I measure it anyways.

Half a medium banana is about 4 oz. I'm sure that they mean w/o the peel. A 1/2 oz one way or the other is not going to make much of a difference especially in a carb up meal.
