Xylene is obsolete for mescaline extraction. It's very toxic and one of the worst smelling solvents in the world. D-limonene is more effective, non-toxic, 100% natural, and it actually smells like oranges instead of the insides of a car engine.
Take a look at these two techs based on d-limonene (xylene could be used instead but with smaller yields):
Pure white mescaline HCl from cactus using d-limonene (orange oil) Non toxic food safe extraction of mescaline using d-limonene (orange oil) The first produces mescaline HCl. Not a mixed alkaloid extract, but 99% pure white odorless mescaline HCl if done right.
There is no real advantage to using sulfuric acid. In fact it’s extremely dangerous. I highly recommend not using it at all. You can get the same level of purity with hydrochloric acid in that tech above if you clean it properly. Plus the end result is more potent by weight.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
