It has always been assumed that when a crew is faced with an emergency the pilots would not benefit from an injection of the hormone as this might cause overactivity and rushed decisions. The cabin crew however would benefit from as much as they can secrete, when it comes to say an evacuation.
This is the basis for the flight deck's duty hours being more restrictive than the cabin crew's.
