Why is this never even brought up by the Detective or Unit Bravo? (Spoilers)

Maybe I've just missed it, but why is >!drinking the Detective's blood!< never brought up by the Detective or the team?

There are numerous situations in Book 2 and 3 where I think it would have made sense for the Detective to at least suggest it. Overwhelming odds? Backed into a corner? The detective literally has the ability to >!make Unit Bravo superpowered. !<

And as established in Book 1, Murphy proved that it does not even take much. >!A few drops of blood could power M, A, N, or F up to quadruple their abilities for a couple of minutes in a fight.!<

Now, there are good arguments against it, I know. >!The detective's blood may have addictive qualities, like a drug,!< and making M >!superpowered!< could potentially be very bad >!by breaking their memory locks, etc.!<

I just find it weird that it has never even been addressed or brought up.
