is just to show how to need be looks 2b34m because much people made from dirty 2b34m and then thing they get pure methylone but first need wash good 2b34m and made him pure then they get pure methylone if they made good synthesis
brother, I'm not an expert, I can't speak, only experts on this forum can describe their synthesis in chemical language. I only know chemistry. Yes, that's my fault, I like to show off
I think that he dissolved the 2b34m with a non polar solvent, maybe THF, DCM, make some washings with water maybe with bicarbonate, dried the solvent with magnesium sulfate and let it crystallise evaporating slowly the solvent.
I have some 2b34m from china that is brown and didn't obtain high yields. Maybe I will try to purify.
