It's very simple. You just need the right solvents.
Wash about 2-3 times with acetone or until you’re left with a very light tan smelly powder. Acetone cannot wash away the smelly alkaloid, no matter how well you wash your mescaline HCl. You then do 1-2 washes with 99% IPA or until all the color and odor is gone. That leaves you with pure white odorless mescaline HCl. All of the other alkaloids are either soluble in acetone or soluble in IPA while mescaline HCl is not soluble in either solvent. You can’t do these purification steps with mescaline acetate because it’s soluble in both acetone and IPA.
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.
