What would a persons body be able to do if there was more adrenaline pumped in it than usual?

Question

i always thought of it like a dumbed down "Eight Gates (Naruto)" type thing. Am I right

Answer 1

I'm not really sure what "Eight Gates" is, but when you get a burst of adrenaline, its like a big burst of energy or power.  Like, when you get in front of a big crowd and you have to perform, you will get a burst of adrenaline, and feel more energetic and powerful.

Answer 2

you'd probably have a heart attack.
