What happened to my DMT (FASA)?

I dissolved 750mg self-extracted DMT (white and yellow crystals) in 40ml of acetone.
I dissolved 250mg fumaric acid in 40ml acetone.
I added the DMT acetone solution to the fumaric acid acetone solution and let it stir on a magnetic stirrer. It instantly became milky white, as expected. After half an hour or so I stopped the magnetic stirrer and could see lots of white particles floating around in the solution.
I poured off the solution into a glass dish. A bunch of powder remained stuck in the beaker, so I added another splash of acetone, swirled it, and added it to the glass dish.
I let it all evaporate in a porch overnight. It was a cold night (probably under 5°C).

Contrary to my expectations, I did not find fumarate crystals this morning but the small amount of goo that you can see in the pictures attached here. It smells of DMT and has no chemical smell.
The acetone came from a bottle that had already been tested last summer with the evap test and had passed it.
There is no way that water or something could have dropped into the dish overnight.

What happened and is this safe to consume, provided I dose volumetrically?

Thanks ahead.

This is what happens if you add too much FASA and/or stir it.
Ideally you should have picked the FASA solution with a pipette or seringe and add it drop wise as slow as possible. Like add 10 drops, wait a few minutes and add a few more drops and so on.

I just FASId half a gram of yellow spice the way I just described and this was the result even before the IPA evaps half way. (See picture at the end)

I had a goo like that a few times, if you spread it along the dish and let it rest a few days it crystalizes most of the times. Depending on the climate where you are and the levels of humidity.

Hello again 🤗

Acetone is hygroscopic as well - perhaps this compounds the goo issue if the stoichiometry leans towards the 1:1 fumarate. Maybe DMT hydrogenfumarate is more hygroscopic too.

Fiddling around with this FASA stuff a few years back was rather frustrating, ime. It does sound like you may have misapprehended the process, however. Once the crysals have formed - they should be 2:1 DMT fumarate, which is insoluble in anhydrous acetone - you need to let everything settle, then decant off the acetone, where any excess fumaric acid should remain.

Unless you've managed to titrate the amount of fumaric acid with absolute precision (highly unlikely), evaporating the acetone along with crystals will deposit the excess fumaric acid as we've seen here.

The low temperature evaporation almost certainly contributed to the absorption of moisture too. Keeping the goo at (warm) room temperature for several days should see it hardening up, but you may want to wash it with nicely anhydrous acetone after that to remove any excess FA, which otherwise would throw your dosing off a bit.

Yes, I played a bit fast and loose with the amounts and followed wrong instructions from entheogeninsight.com (a source I used to trust in but that I've since learned is often sloppy, and now for the first time plain wrong, it would seem). Lessons learned... Thanks.
