Summary
Butylone is a synthetic cathinone structurally related to MDMA and methylone, but with milder entactogenic effects and stronger stimulation. It was first synthesized in 1967 but remained obscure until 2005. Reported to be less potent than methylone, with more dopaminergic stimulation and less serotonergic euphoria. User reports indicate anxiety and dysphoria are common, especially with redosing. Very limited history of human use with minimal toxicity data.
