What substances are released within the brain that back make smaller aching and create a attitude of well-being?

I know the answer is not Endorphins. It has a run (-) somewhere near the front.

Answer:
Endorphins are a class of hormones and include basically 3 types. They are amino acid residues of ss-lipotropin that bind to opiate receptors surrounded by various areas of the brain and hold potent analgesic effect. They are peptides produced by the pituitary gland and the hypothalamus in vertebrates. To date, four groups of endorphins (alpha, beta, gamma and sigma) enjoy been identified. Beta-endorphins are the most potent endogenous opioid that affects both physiological and mental processes.
Even though I really thought this answer be endorhins, I did a little research and the answer could be any of these two: opiate or an opioid. Wikipedia describes endorphins being "like" these.
I ruminate it is either epinephrine, serotonin, or nor-epinephrine.
Endogenous opioid peptides (opioids produced readily in the body).
