Several people asked me, what's the difference between epinephrine and adrenaline? Adrenaline is secreted from the adrenal glands, which sit right above our kidneys. Epinephrine is the exact same molecule, except that it's released within the brain. Epinephrine and adrenaline are basically the same thing. And they tend to stimulate agitation and the desire to move.
