Basically what I have so far is this list:
3-CMC 3-MMC 4-CMC 4-EMC 4-FA 4-MEC 6-APB 6-APDB Methylone
Of these I've only tried 6-apb, however it was a recent batch and I think there were problems with it. It is the sucinate form, not the hcl form. And it might of had 4-apb in it from an intermediate reaction. Either way, it wasn't nearly as good as many older trip reports made it sound.
I've heard 4-fa is good, but is more like a stimulant than empathogen.
4-mec sounds interesting from some trip reports. Only because it seems to be super addictive, and how could it be so addictive if it wasn't good (I'm kind of joking but not
I have not researched the other drugs listed in depth.
What else should be added here? What should I try next?
I've read a little about 5-mapb, it should also be a RC empatheogen. I'd also like to find that alternative to MDMA so I won't have to deal with possible neurotoxicity, but I have not tried any other empatheogens than MDMA. Best of luck to you finding what you search :)
