Pure DMT fumarate from freebase DMT.

To make pure DMT fumarate from freebase DMT the following procedure from SWIM’s notes works great



EDIT: DON'T TRY THIS TECH!!! There's an error in it. SWIM is looking into this and will fix this tech. Until then DON'T TRY IT. It doesn't work as stated. SWIM thinks maybe the acid was MISLABELED IN HIS LAB.

Very nice.

Where does one go about getting fumaric acid? Is this a watched chem?

I doubt its watched its used for many things food additive etc. I think it should be cheap and easy to get.

excellent idea also.

also one small question. just curious why the fumarate could the same kind of benefits come from making tartrate or some other salt? i believe this was the form deemed safe to inject in humans by the FDA?

DMT fumarate is the only form approved for research by the FDA. Fumaric acid is safe and is commonly used in the food and wine industry to give a tart flavor. It’s also formed naturally in the human body. It’s considered a food additive. I never heard of it being used to manufacture commonly abused illicit drugs. It is not a watched chemical.

Most other salts like DMT tartrate, DMT citrate, DMT acetate, DMT HCl, etc., are very hygroscopic. They will crystallize in a vacuum desiccator or in the presence of dry heat, but after removal they almost immediately start absorbing water from the air becoming a wet goo. This poses a problem, making it hard to measure doses from the wet goo, and I believe the absorbed water shortens DMT’s shelf life.

I’ve seen many others on different forums post failed attempts at making various salts of DMT. Nearly all of the attempts end up with a wet goo. This is because only a small handful of acids make non-hygroscopic DMT salts. Most common acids are somewhat hygroscopic, and become super hygroscopic when combined with DMT. Fumaric acid is very non-hygroscopic, and so it forms non-hygroscopic salts with DMT that stay dry even in humid environments.

interesting, but now many people would use it with an MAOI, a necessity when dealing with salt form? seems good from a storage standpoint, but most folks are probably pursuing the free base form for vaporization. with free base, storage in a suitable non-polar in the freezer likely keeps it stable indefinitely.
SWIM's curious about transdermal application with dmso, though not sure how effective it is in terms of bioavailability by this route.

DMT fumarate is best for snorting, taking sublingually, injecting, taking intra-rectally, or taking orally with an MAOI. If a person wants to smoke DMT, they need freebase DMT. SWIM thinks smoking it is a waste. The trip is too short. SWIM prefers the other routes of administration because the trip is much longer lasting.

SWIM tried DMT fumarate with DMSO sublingually. It doesn't burn like freebase DMT does, but it's just as effective.

interesting

fumarates are definitely stable, common in so many pharms. sublingual sounds enticing.
an extraction with limonene converted to the fumarate salt. sounds like a most entertaining lemony wacky wafer.

The DMSO + DMT fumarate combination is weak sublingually, but it works. It's just like snorting DMT. It takes 2-3 times more to be effective. SWIM never tried it without DMSO, and doesn’t really know if the DMSO actually helps or not. DMSO makes a nice tincture solution for DMT fumarate though.

On the subject of DMSO, is there a ratio of alkaloid to DMSO that is best? Should the DMSO be saturated with the alkaloid or very dilute?

does snorting the salt burn much?

Freebase DMT burns a lot, but not as much as 5-MeO-DMT.

SWIM only snorted DMT fumarate once and it was a small dose. SWIM didn’t feel any burn. It's a little irritating in the nose, but that's the case for pretty much anything snorted. Maybe if more is snorted it might burn. If SWIM tries a larger dose SWIM will post his experience with it.

yes that would be very interesting. would like to know how much longer the effects last and how much slower it comes on.

what color is the fumaric salt? thanks

edit: too bad MEK is a list 2 chem, are there any alternatives?

any1 know where to get fumaric acid? the only places online seem to be the chemical places and would really like to go another route.

You can find it but you have to search around. SWIM got some from a friend who works at a winery. They use it to add tartness to the wine. You can probably get it from a local winery supply shop.

Try searching www.ectrator.com or www.ebay.com. I think I remember seeing it at one of those places recently. I've seen it at before at eBay for sure. Or try Google Products. I know Google Products lists it, but mostly in capsule form or usually from a chemical supply store.

SWIM says, DMT fumarate forms completely colorless, long clear pointed crystals in MEK that look like the kryptonite crystals seen in the superman movies. They will be lightly yellow or amber colored if impure.

As an alternative to MEK, 99% isopropyl alcohol can be used to remove the excess fumaric acid. Fumaric acid is soluble in 95% isopropyl alcohol and below, but it’s insoluble in 99% isopropyl alcohol. Probably 99% ethanol could be used but SWIM never tested that. SWIM likes MEK for removing the excess fumaric acid because it evaporates faster than isopropyl alcohol. Plus it’s easier to get (local stores have it over the counter without need for ID) and much cheaper in SWIM’s area.

Could someone please pm me where to get fumaric acid...I cant find it in less than 50 lb amounts. I checked wine sites etc and none offer it. Please!

Search in online winery shops. Also google: food grade fumaric acid.

Hey Ron

Nice work,
I'm wondering did you have any problems crystallising or did it just happen by itself?

I've tried to do this many times but failed every time the last attempt used a procedure derived from Tihkal:
1. Dissolve some dmt in methanol
2. dissolve some fumaric acid in methanol
3. Neutralise or slightly acidify the dmt solution with the fumaric acid solution
4. Add two volumes of isopropyl acetate and upon cooling crystals should precipitate

nothing happened

the appropriate amounts of dmt and fumaric acid were also dissolved in 95% ethanol, stirred well and left to evaporate producing an oily residue. After two weeks it crystallised itself but surely that's not right..


Anyway, thanks for the tek!
I'll have to give this a shot soon

SWIM had no problem crystallizing it in MEK or any other solvent. It crystallizes very easily, usually before the solvent evaporates. He always uses pure clear/white DMT extracted from Psychotria viridis that was freeze precipitated in heptane before making it into DMT fumarate.

SWIM found DMT from Psychotria viridis is usually much cleaner DMT than the DMT from Mimosa. SWIM doesn’t extract from Mimosa anymore. There are too many unknown alkaloids in it. SWIM doesn’t feel that he can really get pure DMT from Mimosa, even when re-crystallized many times, he seems to notice something else is present other than DMT. Maybe it’s just SWIM’s imagination, because he knows Psychotria viridis contains about 99% DMT usually, and almost nothing else.


SWIM never tried that technique so he can’t comment on it.

Something is wrong. You should get pure clear crystals as soon as all the solvent evaporates. DMT fumarate is very easy to crystallize. Even if it doesn’t crystallize it will dry to a completely clear/white flat solid that can be broken into a bunch of tiny powdery crystals. It never forms an oil of any kind. Its always a brittle crystal texture whether it crystallizes or not.

It sounds like you have DMT that isn’t pure. DMT N-Oxide is probably in it and maybe some plant oils. Was it yellowish? If so, it’s not pure.

Do it with freshly freeze precipitated pure clear/white DMT crystals.

To freeze precipitate DMT SWIM dissolves 1660 mg of impure yellow DMT in 100 ml of warm heptane (not hotter than 50 C). Once it’s all dissolved, if there is any yellow oil at the bottom of the container (DMT N-oxide and oils), swim carefully pours the heptane into another container leaving all the yellow oil behind. He then evaporates the heptane down on a hot plate (no hotter than 50 C) to about 50 ml (or until the heptane gets cloudy) and then he puts it in the freezer. Within an hour DMT crystals always form. It can be left overnight to be sure to get all of the DMT. SWIM just waits 4 hours usually and pours off the heptane. He then lets it dry overnight at room temperature without a fan.

It was pure..
hmm, food for thought

acacia obtusifolia is the source
