The acetate salt is supposed to be most bioactive and I would assume citrate would be right under that. But this comes with a huge disadvantage. The acetate salts even at 99.99% are waxy and stick to things. This of course wouldn't be much of an issue if you are stuffing them straight into gel caps.

I find Peruvian Torch to be much more predictable in concentration which is great for making the Incan sludge tea. If extracting, cheaper San Pedro will do just fine as you are controlling dose with nearly pure mescaline. I have seen San Pedro with greater concentrations than torch and also with very little.

Here's a quick top-of-the head idea: Adding strong magnesium sulfate solution to a solution of mescaline citrate - would that potentially precipitate mescaline sulfate crystals through the common-ion effect? Sort of like a Manske for mesc.. This seems so simple that surely someone would have discovered it by now if it worked

It's all about which are the least and most soluble of:

Mescaline citrate; magnesium sulfate

Mescaline sulfate; magnesium citrate


I'm a teeny bit surprised to hear of benzyme (of all people) attempting to evap sulfuric acid. At 1 atm it boils at 338°C, What kind of hard vacuum are you pulling to get rid of that in a water bath?!

a pfeiffer duo 2.5. it is a li'l beast of a vac. pulls down to 7 or 8 microns

Checked the tech spec: ≤ 6·10^-3 mbar. A beast indeed!

So, according to this nomogram you'll have no trouble evaping sulfuric at all
