RCs What Is The Difference Between Mephedrone & Methedrone?

Hi, i am confused as to what the difference was between Mephedrone, and Methedrone.. Was Methedrone circulated aswell as mephedrone during the times when it was legal? Was there a difference in effect?.. Which one was invented 1st, and were they invented by the same people?. Why could i never seem to find Methedrone suppliers?..

I hope someone can answer my questions

Thankssssssssssssssssssss.

Same thing.

It's not the same thing; use google/wikipedia next time.
