Pentylone (β-Keto-Methylbenzodioxolylpentanamine, βk-Methyl-K, βk-MBDP, methylenedioxypentedrone, or 1‐(3,4‐methylenedioxyphenyl)‐2‐(methylamino)pentan‐1‐one[1]) is a stimulant developed in the 1960s.[2] It is a substituted cathinone (a type of substituted phenethylamine). It 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".[1] Reports indicate side effects include feelings of paranoia, agitation and inability to sleep, with effects lasting for several days at high doses.[3]
