Okay... So I'm at a loss.
Acacia confusa is a beautifully tryptamine rich source, but the NMT is not exactly desirable in the final yield, though I would happily pull it in a final full-spectrum 4tehlulz.

That being said, I have found a number of teks, and I would like to inquire as to what might be anyone else's say on what got them the best yield with this beastly source of spice.

I've seen a tek which outlines a way to precipitate without freezing, i.e. just let the jar sit, and the tekkie said that the NMT doesn't pull this way. I'm wondering if anyone has any experiental validation of this. It really seems too good to be true.

Also, naphtha or xylene? Or if anyone can recommend even a better solvent...
Just digging here.

Why isn't NMT desirable?

i'd encourage you to pull all of the alkaloids the plant has on offer as they make acacia confusa what it is.. otherwise its just generic dmt (which is nothing short of amazing but its even more interesting when it has the "signature" of the tree you've extracted from imo).. some of the coolest extracts i've tried are those with a range of differen't alkaloids

perfectly worded.

I use the STB method, no freeze/thaw either.

Bark + Water + Lye + pot for warming solution in + 30 mins , Pull with naphtha.

THere are ways to convert the NMT to DMT via Co2/dry ice reaction. Or ways to separate it as well. But as acacian said, you want that Acacia NMT in their for the signature. NMT + DMT is my preferred DMT route. NMT makes the ride gentler and smoother without diminishing the experience. I dont see why ACRB isnt the preferred source for most psychonauts. Full spectrum is just as awesome but different and lingering(ACRB full spectrum).

I smoked 15mg of ACRB full spec and could see High Definition and vivid colors for 20-30 mins easy vs the 5-10 mins max with straight DMT.

ALSO, you can simply just do a full extraction ACRB, then freeze precipitate and separate the white fluffy crystal DMT from the NMT/DMT goo mix, then scrape the goo separately for a heavy NMT light DMT product, along with pure white DMT crystal. Its totally possible to get white powder crystal DMT from ACRB. I did on my second ever extraction.

EMBRACE THE NMT GOO

Idealy you want to not use Naphtha but instead do your extractions with food safe chemicals

I recently switched from STB + naphtha to STB + d-limonene. Resulting in D-limonene with freebase DMT in it. You then "salt out" the DMT by adding dropwise a Fumaric Acid Saturated ISO Alcohol solution into the DMT D-Limonene resulting in an instant reaction creating DMT-Fumarate. The DMT-Fumarates fall out of the d-limonene and to the bottom of the jar. Place in freezer for 12 hours, then pour off/decant D-limo/ISO mix away from the DMT-Fumarates and air dry the jar with a fan for 24 hours. Now you have DMT-Fumarate extracted with totally safe chemicals. FOOD SAFE.

Now you have DMT-Fumarate that needs to be converted to DMT Freebase. You disolve the DMT-Fumarate in hot water, then again "salt out" the DMT by adding drop wise Sodium Carbonate Saturated Water. This will base the solution creating DMT Freebase. Pour through a filter to catch the DMT Freebase and dry it. If it gets caught in the filter then you can use USP Grade Acetone to dissolve the Freebase DMT away from the filter and evap the acetone on a dish to yield CLEAN ASS FOOD SAFE DMT Freebase.

Lesson #1 in how to confuse the newcomer:

(nice tekage though magic9)

It's not un-desirable per se, I just want some (nearly) pure DMT. I actually rather like the oils, but I'd also like to have some actual (for better or worse) crystals to REMOVED for some weed (since I refuse to actually SELL it, for moral reasons) if you really want to know, and just to have that "pure crystal" smoking experience.
I don't mind getting the jimmy jammy junk after having about a gram of pure-ish crystals.

Unless there's another reason that I'm just getting smokable (and incredibly exotic smelling) goo and not crystals, I'm blaming the NMT content and the small amount of lipids that I didn't get from my last TEK because I STB'd.

FumA is food-grade? You learn something new every day lol... Personally i would lean towards an acetate or citrate. I have quite a good amount of citric acid on hand that I use for pretty much everything, including DXM extractions.
Sodium carbonate is as simple as tossing simple baking soda in an oven on low heat for a while, right?
Also, not sure if sourcing, but if anyone could tell me a good brand and where to obtain a less-than-a-who-will-ever-use-a-gallon-in-a-reasonable-time d-lim, that would be very nice. Besides, a gallon of d-lim is pretty expensive.
And also, I've heard that d-lim yields ruddy crystals. Is this true at this level?

Most the time my acacia confusa extractions were quite strong in effect when vaped..
But the last couple times [very recently]..i extracted from my one kilo package of whole bark i got a smaller amount of very fine looking crystals..[from 100grams of acacia bark!
The total i got this time from the 100 grams of bark was only about [100 to 250 mgs of crystals!]
That was very disapointing..but i did pick out only the smallest thinest bark chips for easy grinding.. and i wonder if those bark peices were from limb bark?
Upon vaping these crystals up to 40 mgs i found it to be very weak compaired to past extractions vaping total extract goo.
It does apear that acacia total goo is stronger in effect than acacia crystals??
Why is this?....Maybe the crystals were mostly NMT?
Maybe all my acacia bark is not even in NN DMT alcaloid content?

Why get whole bark when finely powdered or even finely shredded bark is just as readily available?
Personally, I think that finely shredded is preferable, since it makes it easier in the end to filter it off. Also, how many times were you washing it?
The rule I've seen is a diminishing return of 70% per wash or something like that, where three wash will effectively give you 95%+ total alkaloid yield...

Again, I agree with this, but I want that generic DMT on hand for Mod Edit: There is No discussion on trading of drugs here at the Nexus.
Please refer to the Attitude page . Thankyou purposes. People recognize DMT as a crystal, not as an oil... Hoping I can trade for weed, shrooms or LSD or something at the UNI amongst my psychonaut friends who really want the DMT experience.
Believe me, I love the goo, because it's a very exotic trip, and more fluid instead of the archetypal mandela of sharp geometrics with the visuals. Mixed with a little TOOL or Shpongle, I feel like I've gotten lost in the jungle.
I want to keep that experience to myself. It's a real treat. Plus it smells really exotic and strong.

Perhaps your friends should check out the site. Then they'd know goo is alright. Just a thought

Best yield %?
Herbal Percolator with large amounts of vinegar, and then taking the remaining plant material, soaking it in vinegar, letting it sit for a week.

Prior to using the percolator you want to place the plant material slightly submerged in water in the freezer, freeze then unfreeze x3 to burst the cell walls to get the dmt trapped inside (supposedly).

Naphta is fine, just do 10 shakes while letting it settle between each shake, then percipitate the dmt, then redo the shakes 2 more times.

Should be near max yield.

Step 1: Read The Attitude Page.

Step 2: Recrystallize.

or

Pull with minimal hot naphtha
let hot naphtha sit out at room temp for a while until (mostly NMT) goo crashes out
pour off naphtha into new container
freeze-precipitate
crystals.

then

Re-x (mostly NMT) goo that crashed out, a couple times
freeze-precipitate
more crystals.

This method is described in more detail in Thick-Light's tek.

Letting it sit in vinegar for a WEEK?

I read in another post (just searched 58pgs, but couldn't find it) about someone accidentally leaving it sitting for over 52 or 56hrs and they said it was far too long.. They mentioned it changed from green to losing its color..

I don't see any reason that letting the rootbark soak in vinegar for a week would hurt anything. I can't say for sure whether or not there would be any benefit to soaking for a week versus soaking for a couple of days, but I would guess that there probably wouldn't.
