Methylone + mdma (?)

[citysmog]

From what people have told me this is a great combo that makes the roll last longer, but a quick search on the search engine hasn't really provided me much of the information I need. Also has anyone tried methylone +mda, would there be any down sides. What if ketamine would be added to either of these mixtures would it be problem. Thanks alot

I doubt there would be any advantage to combining them, and it would likely increase the incidence of sideffects. I can't say I've ever heard of someone combining the two!

Let alone methylone + MDA, which sounds like a great way to mess up an MDA experience.
