Epinephrine and adrenaline are the same molecule, with epinephrine being released within the brain and adrenaline from the adrenal glands, both stimulating agitation and the desire to move.

“Several people ask me, what's the difference between epinephrin and adrenaline. Adrenaline is secreted from the adrenal glands which sit right above our kidneys. Epinephrin is the exact same molecule except that it's released within the brain. And so people use these phrases or these words rather interchangeably, epi means near or on top of sometimes and neph, neph Anytime you see nephron or ph it means kidney. So it means near the kidney. So epinephrin actually means near the kidney. So it was used originally to describe adrenaline, but epinephrin and adrenaline are basically the same thing and they tend to stimulate agitation and the desire to move.”
