Methylone

Research chemical

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.

Harm reduction

This entry comes from the extended library: it is a less-studied substance with fewer independent sources.
Unknown potency is the main risk with novel substances — start with a fraction of any published figure and never re-dose before the full onset has passed.
Test with reagents and, where possible, a lab service. Fentanyl and nitazene contamination is not detectable by eye or by reagent alone.
Avoid using alone, and do not combine with other drugs while you are learning how a new substance affects you.
