Does methylone still exist in the wild?

[Missingno]

Methylone, AKA Bk-mdma) was my all-time favorite RC. I hadn't seen it in ages, so I started poking around, and the main answer I found was that nobody makes it anymore since it uses the same precursors as MDMA, and the lovely mad scientists who made and sold the stuff now just made regular MDMA, since MDMA will sell for more and is therefore a more lucrative use of the precursors.

Does anyone have any info on this? Is there any of it still out there in circulation? One person even said the only way to get it currently is to make it yourself or hire a friendly mad scientist to do a custom synth.
