If using citric acid (which is the recommended choice), prepare a solution of citric acid powder with a small amount of water. I recommend using citric acid because unlike hydrochloric acid, it is food-safe and safe to handle, and unlike either hydrochloric acid or vinegar, it is available in pure form. I have been told that using hydrochloric or acetic acid has the advantage that both are volatile and that excess will evaporate off, unlike citric acid. However, since neither are easily available in pure form, it is still probably better to use citric acid. Beware that if you do use hydrochloric acid and let it evaporate, the fumes can be hazardous and the evaporation should not be done where you might breathe in the vapors.

Mescaline free base = Exact Mass: 211.121 g/mol
Citric acid = 192.12 g/mol
H2s04 = 98.079 g/mol
HCL = 36.458 g/mol
98.079 + 211.261 = 309.34 g/mol mescaline sulfate
211.261 + 36.458 = 247.719 g/mol = Mescaline hydrochloride
This makes the sulfate 11% heavier than the hydrochloride, which really is not that big of a difference, but still must be taken into account when weighing out doses, so, you would need 11% more of the sulfate than you would of the hydrochloride...
from this perspective it's the hydrochloride salt which would be the most desirable, though as long as one understands that the dose must be adjusted to compensate for this, I suppose that ultimately it really doesn't matter, as you would still be getting the same amount of mescaline provided you compensate in dose for the weight change...

This isn't actually correct,
citric acid is triprotic
h2so4 is diprotic
hcl is monoprotic.
your calculations are correct for HCl, not the others.
0.5M worth of H2SO4 will neutralize 1M eq of mescaline freebase, i've tested this myself.
Citric acid might not completely deprotonate, but my bet is it probably mostly does, mesc is a strong base.
so for example, mesc sulfate = 211*2 + 98 = 520g/mol
2Mol mesc sulfate = 1mol mesc freebase
10g of mesc sulfate = 10g/520g/mol * 2
.038mol*211g/mol = 8.12g freebase
compare to 10g mesc HCl = 8.52g freebase
Sulfate 23% heavier than freebase
HCl 17% greater than freebase
only 5% difference
178 mg mescaline HCl = 200 mg mescaline sulfate. -erowid
100 mg mesc sulfate = 89.0 mg mesc hydrochloride = 75.9 mg mesc freebase
So, with the two salt forms, there's only about an 11% difference. If
someone gets confused between one and the other, the mix-up is not
going to cause major havoc.

Mescaline sulfate
Mescaline sulfate | C11H19NO7S | CID 71609 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.pubchem.ncbi.nlm.nih.gov
Sulfate: In the sulfate, there are two mescalines per H2SO4. To
complicate things slightly, the sulfate exists as the dihydrate,
meaning there are also two H20s per unit cell. You end up with:
(mesc)2.H2SO4.(H2O)2
mesc 2 * 211.261
H 6 * 1.008
S 1 * 32.068
O 6 * 15.999
-------
556.632 grams per mole of (mesc)2.H2SO4.(H2O)2
But you want that in terms of one, not two, mesc molecules. So divide
by two:
278.316 grams per mole mesc sulfate [mesc.(H2SO4)1/2.H2O]
100 mg mesc sulfate = 89.0 mg mesc hydrochloride = 75.9 mg mesc freebase

I would advice against the MEK cleanup. Your MEK and methanol must be anhydrous so you won't lose the product. There are better and more reliable methods using water and acetone or even just water, depending on the type of mescaline salt you have produced. You can also backsalt it if you really want mescaline fumarate.

Cleanup is not as difficult. But blue.magic is right, water is an enemy!
