Endorphins are best described as:

Endorphins are endogenous opioid neurotransmitters that help control pain and generate feelings of pleasure. They’re chemical messengers produced in the brain (and released by the pituitary) that bind to opioid receptors, dampening pain signals in the spinal cord and often producing analgesia or euphoria. They’re not electrical impulses traveling along neurons, not glands producing hormones, and not long fibers of neurons; instead, they are natural body chemicals that act like opioids at the neural level.
