Pentylone, also known as ò-ketoN-methyl-1,3-benzodioxolylpentanamine (bk-MBDP), is a stimulant developed in the 1960s. It is a substituted cathinone that has been identified in some samples of powders sold as "NRG-1", along with varying blends of other cathinone derivatives including flephedrone, MDPBP, MDPV, and 4-MePPP. It was also found in combination with 4-MePPP being sold as "NRG-3". Reports indicate side effects include paranoia, agitation, and insomnia, with effects lasting for several days at high doses.
Pentylone acts as a serotoninâÂÂnorepinephrineâÂÂdopamine reuptake inhibitor (SNDRI) and a serotonin releasing agent.
Pentylone is banned in Canada, Germany, Sweden, the United States, and the United Kingdom.
