Injecting in other places…

Soooo we’re supposed to take our insulin in fatty places like our stomach or back of arms or butt. I googled what would happen if I injected somewhere else like my calf or my forearm and the results basically said the insulin would absorb too fast.

Is this true? Wouldn’t this be a good way to correct highs? I know this is a terrible idea but just curious if others have insight on this!
