Update on the latest test (post #23) using more Na+ resin (also more shaking):

- The water before the Na+ resin pull is changing color to a green-blue, while the water sampled after the ion exchange pull is not. This is a good sign indicating that Na+ resin can also absorb psilocin. If anyone is interested in how it looks I can take a picture later today.

- After the oven dry a flaky residue is obtained (image below for reference). This time I used less tartaric acid and also less fan time and more oven time. Some blueing was observed during the long oven dry (can't be good for final potency). Indeed, a bioassay showed little to no activity. 

To summarize, it seems like the Na+ resin is capable of binding to the psilocin (and other stuff). However, the oven dry could be a place where potency is lost.

Will need to troubleshoot this. Mindlusion had some suggestions in the chat last night (thank you).

One thing that will be tried next is acetone crashes. If acetone is added to the alkaline ethanol pull, proteins are expected to crash put. After that, when adding tartaric acid more proteins should crash out in salt for (maybe also the psilocin salt). Will do these kind of tests when possible.

This is all still very much work in progress.
