Butylone has a methyl substitution at RN, a substitution that's shared with MDEA, ethylone, four-MEC, and selected other stimulants and entactogens. Moreover, butylone consists of substitutions at R3 and R4 with the phenyl ring with oxygen groups. These oxygen groups are included into a methylenedioxy ring via a methylene chain. https://miloirqut.sunderwiki.com/1486560/top_guidelines_of_buy_ephedrine_powder_online
