Adrenalin is produced from the adrenal  gland along with one other hormone. It can kill you and raise your risk of a stroke, myocardial infarction, athroma and thrombosis. Adrenalin does this by raising your blood pressure so then the walls of the arterys thicken reducing the volume of blood going through. This in turn can leave more chance of thrombosis or blood clot.

Dont play with internal chemicals ales you know enough about them. Also adrenalin would be near impossible to control ales you know its chemical signiture.
