My point was that insulin only works once it gets absorbed into your blood. It does not work in the muscle or fat. From those places it eventually gets absorbed into the blood, where it starts to work.

So the “eventually” part, the time you are waiting on it to get absorbed into the blood, that is the part that makes insulin so slow.
