Hexen is a stimulant of the cathinone class. HEXEN (N-Ethyl-hexedrone; NEH) stimulation is believed to be caused by its affinity as an NDRI (norepinephrine-dopamine reuptake inhibitor). HEXEN is closely related to hexedrone, with an added ethyl group on the carbon chain containing the nitrogen. This addition makes it about 3x as potent as hexedrone. It is also known as HEXEN; NEH. N-Ethyl-hexedrone (also known as HEXEN; NEH; a-ethylaminocaprophenone and N-ethylnorhexedroneand) is a research chemical that is in the cathinone group.
