3-CMC CRYSTAL, 4-MMC > bk-MDMA > 4-CMC > 3-CMC > 3-MMC > 5-methyl-ethylone > Butylone > Ethylone Apparently, this “Clephedrone” (4-CMC) that hasn’t really made a significant appearance on the RC market is good stuff. And not explicitly scheduled in most places AFAIK. Safety profile largely unknown, of 2C-B in most areas. It is up to researchers to know the laws pertaining to these compounds in their region, however.
