Butylone contains a methyl substitution at RN, a substitution that's shared with MDEA, ethylone, four-MEC, and certain other stimulants and entactogens. Moreover, butylone incorporates substitutions at R3 and R4 in the phenyl ring with oxygen teams. These oxygen teams are included right into a methylenedioxy ring through a methylene chain. https://davidl097vag2.actoblog.com/profile
