Excess fumaric acid contamination in DMT fumarate?

[Ruffles]

There is a large and honorable discussion on diversity of spice (aka jungle spice vs white spice vs full spectrum etc) but I have not seen a lot of debate on purity of spice from FASA derived spice (or other types of acids in saturated acetone).

What do you think? Does FASA tek give out pure DMT fumarate? How user friendly is FASA in terms of DMT purity? If you overshoot on the fumaric acid content in your loaded nonpolar solvent does it lead to excess fumaric acid in the precipitate? Does the nonpolar solvent make a difference for purity (xylene vs hexane vs naphta vs dc vs etc)? How effective is recrystallization to cleanup excess fumaric acid or does it even do that?

In my experience there is so much variation between FASA batches coming from the same MHRB that I just don't know what could have caused it. Of course, we don't apply best laboratory practices or ISO standards for kitchen chemistry so batches should vary. Plus variations in procedures leads to learning by trial and error.

I do think that some DMT fumarate batches are more potent than others and I would attribute it to having less fumaric acid contamination.

An example: loaded xylene FASA'd and the resulting crystals are dissolved in boiling IPA. 2 days at room temperature and collect the resulting chunky orange or pale brown crystals. Put same IPA into 4 Celsius for 2 days and then collect light yellow spiky crystals. Put same IPA into - 20 Celsius for 2 days and collect transparent white crystals. Now, pound for pound, the room temperature crystals are far more potent than the cold temperature crystals. I attribute this to it having less fumaric acid contamination, but I really don't know and can't analyze them properly. It is all good DMT for consumption, but so different from each other, very strange.

This is a big topic and I don't expect a straight answer as there are too many variables. Please share your experiences in peculiar batch differences... Looks, taste, effects, impressions, opinions.

Fumaric acid crashes from FASA when added to naphtha and similar aliphatic hydrocarbons unless they're spiked with acetone beforehand, so you might want to take that into account.

You may have to determine the DMT content of the various colours of crystal by very careful extraction of the freebase, but you'd likely need a super-accurate balance for that to be worthwhile.

Your observations about the different temperatures of IPA re-x are very interesting, so thanks for sharing that data. Many moons ago, my room temperature fumarate also was orange-brown, much as I hazily recollect (fwiw.)

What ROA are you using to compare the potencies of the different crystals? Mine were prepared for research purposes that did not include consumption.

Also remember that if you use acetone, it should be as dry as possible. Read: NO water in it!

There are several teks out there to dry your acetone together with advices to never let your acetone be in contact with the air any longer than needed.

So if you keep it for longer in a container, make and keep it airtight. Acetone and water are like Romeo and Juliette; before you know it they consume their marriage.


Kind regards,

I noticed that the first drops of FASA into nonpolars might drop down a salt to the bottom, needs a little shake at the beginning to prevent that, afterwards it clouds better... Like you said nonpolar spiked with acetone works better.

What was described was compared by IM.

A mini STB conversion is doable and a good scale is not impossible.
