Naphyrone is an extremely potent synthetic cathinone, reportedly 10-13 times stronger than cocaine and more potent than methamphetamine. It carries very high overdose risk due to this potency. Known for prolonged duration, intense comedowns, and strong compulsive redosing tendencies. Many products sold as 'NRG-1' were found to contain other substances rather than naphyrone. Legal status: Controlled as Class B in UK (2010), Schedule I in USA (2017).
