any information about this two piperazines. Solo or combined? I would like to know if anyone would recomend mcpp or meopp; do both combine well? If yes how about the ratio of both substances. I know that most people here on the forum regard piperazines as doggy substances, but there are also positive reports about the two There are just not to many reports; 2 about mcpp and meopp on erowid? What about the meopp? How much mg is needed? Is it enjoyable? Or must it be mixed with other piperazines for good effects?
