Description
βk-MDMA is a cathinone stimulant and empathogen, similar in structure to MDMA, though more stimulating and less empathogenic in comparison. Was very commonly mis-sold as MDMA on the street until it was banned in 2013. The Marquis reagent can differentiate βk-MDMA from MDMA. Less potent than MDMA with a slightly shorter duration.
