Product pH check is coming in at 3.55 (750mg dissolved in 15ml of warm water). This could mean (1) I did not wash out all the citric acid or some other contaminant that can affect pH (but I think I did need to double check), or (2) that the dihydrogen salt is forming: (MesH)H2Cit, or (3), I'm missing something in the logic for the the pH expectations for the different mescaline citrate salt forms, or (4) something else is going on that I'm not aware of.

If it is indeed we are forming the dihydrogen salt, it would be 68% as potent by weight as 3(MesH)Cit which I had been assuming (because of the large pKa differences).

I think this remains an open question at the time. All I can say is that the pH test was not consistent with (MesH)3Cit. Can't draw a strong conclusion though because there are other possible explanations beyond the salt form. Perhaps converting to HCl and back to citrate would be a more robust check (but more work).

This salt was made with with both the "drop acid" and the mechanical shaking methods (I mixed both products together for storage). It may be worth checking salts from the magnetic stirring method and acid drop method separately. I think it should be the same result, buy may be worth checking to make sure.

In other news, there have been some revisions to the TEK from shroombee and me (thanks shroombee):

- FAQ section added
- Cold extraction option added
- Material section expanded
- More references added (including a mycotopia result for whole bridgessi which gave a tacky active potent product).
