How can I get such crystal rocks from 4mmc powder?

Would be great help if any experienced folks could share the methods, have been looking for almost 12 months

Thanks

Would it be possible with 4mmc alone or can we either mix methylone hcl before recrystallization?
Any other cathonone or eupherotic that ceystallizes in big rocks not only crystals?
Certainly seems like a quick cooling method that does not allow complete crystals but instead these crystallized rocks, please advise BB
