NRG-1, NRG-3, naphyrone


What is it?

‘NRG’ is a term used to describe a number of substances (the most common being NRG-1 and NRG-3) which are mostly derivatives of naphyrone (or naphthylpyrovalerone), a man-made ‘designer drug’ with stimulant properties. However, it is important to note that many drugs sold as ‘NRG’ have been found to contain a wide range of chemicals and may have no relation to naphyrone at all.
