Some science behind the scenes


Enkephalin - Leu-enkephalin is an endogenous opioid peptide neurotransmitter found naturally in the brains of many animals, including humans. It is one of the two forms of enkephalin; the other is met-enkephalin. It produces pharmacological effects at both the mu and delta opioid receptors, showing selectivity for the delta receptor. It has a much higher selectivity for delta opioid receptors than mu receptors, and has little to no effect on kappa opioid receptors.
