Noradrenaline and adrenaline mnemonic

Epinephrine is so epic that it acts on alpha1, alpha2, beta1 & beta2 receptors.
Norepinephrine does not act on beta2. Not so epic. It acts on alpha1, alpha2 and beta1 receptors.

Which one is found in circulation and which one is released by nerve endings?
N for Nerves. Noradrenaline from nerve endings only.
Epinephrine is found in circulation.

*sings* I feel the adrenaline moving through my veins.
