Brain hormone associated with "natural highs” (9)

I believe the answer is:

endorphin

(Other definitions for endorphin that I've seen before include "painkiller" , "Neurochemical with analgesic properties - dinner hop (anag)" , "Hormone in the brain with an analgesic effect" , "Opiate-like substance produced in the brain" .)

I've seen this clue in The Times.
