a/b vs stb

[bosch2467]

This has to be answered somewhere here. But I cant really find the answer. what is the difference in end product regarding whether you do a/b or stb?

i know the stb is what most people do because it's less steps or whatever. does the a/b provide a stronger product? cleaner? whiter? or is is the same?

Some starting materials give better results with A/B extraction, because it allows for a defat in the acid stage.

There are further methods, but it all boils down to an assemblage of simple chemical techniques.

from what im understanding. its either you do a/b and you are good, or you to stb but with a wash in the end to supplement for the fact there was no acid bath in the beginning. seems about the same amount of effort to me. guess it depends on your setup though.

do you think there is a quantity of final product difference between the two? or is there a quality difference? or is it just about the same?

The wash at the end is to remove any traces of NaOH suspended in the solvent, see here: The Base in Your Product The inclusion or not of an acid soak phase at the begining of the tek has no bearing on the need to do that wash, as basing requires you reach a strongly alkaline ph of 12 or more in either tek, and it's the remains of this solution that the water wash removes.

I don't think that, done properly, there''s much difference at all in quantity of product between the two. Quality wise it is supposed tthat STB can tend to produce more of the yellow waxy or oily polymorph of DMT due to longer exposure time of the freebase DMT to the strong alkaline solution, since the NaOH is used to break down plant material too.
But I've only picked that idea up from reading here, I've not tried to test it. I'm pretty sure that the oily polymorph is just as active too, but its different vaporisation temperature can result in a need to tune the delivery method differently and result in some claims that it's not as active as white fluffy DMT.
The yellow is also a lot denser than white, leading to dosing variation if not being careful.

The process from extraction to delivery has a few subtleties that affect the outcome slightly, but there's not much you can do to completely fail if you follow a tek reasonably well. It *is* quite easy to burn up your product by overheating it during administration though, so it's tricky to control for stability at either end of the process and determine what is making any difference in experience. ... oh and you have to throw into the ring the fact that psychedelic experiences depend strongly on "set and setting" so the whole "quality" metric is a tricky one!

Anyway all the above is to say that both methods work substantially the same, and as the aim is to get enough DMT for a personal experience then either will do. Don't fall into the over optimisation trap and keep an eye on the purpose of all this

Personally, I use cyb's hybrid AtoB Cybs' Hybrid ATB 'Salt' Tek - DMT-Nexus Wiki which is easy to perform and requires nothing in the way of filtering equipment.

The three posts linked in [Chemistry] Extraction Basics are relatively in depth but approachable. I would suggest a read of any if you find yourself interested.

The following quote is early in the EXTRACTION GUIDE: Principles of Alkaloid Extraction (in relation to N,N-Dimethyltryptamine) and pertanent to your inquiry:

There are 2 main extraction techniques utilised in the extraction of DMT. The acid-to-base extraction (ATB) and the straight-to-base (STB) extraction. Both of these techniques rely on the precipitation of freebase DMT within a solvent. However, in order to obtain freebase DMT, it must be extracted from the plant material. DMT is soluble in acids, and so ATB is widely used. ATB is preferable to STB for only one circumstance; the species of plant material used. Typically, ATB is preferred when using fat laden plant species, such as Acacias. The DMT is located in the central vacuole of the plant cell, so in chemical processing, we try to break apart all the plant structures. This is the reason for acid simmering steps that last several hours. However, when you break apart the entire structure, it is inevitable that you will extract some unwanted compounds, most common being fats and oils. These are harmless, but lower the purity of the final product. In DMT extractions, we try to extract alkaloids only, and leaving behind all the plant fats and oils.

When either extract is done well you'll have similar end results. STB may have more yellow and plant oils like fractals4life mentioned. This is not a negative though. If doing stb with naptha it may behove you to look at then doing a xylene pull or three for anything full spectrum out of the bark ( see Q21Q21's Vinegar/Lime A/B Extraction Tek - Background Information for some interesting information ).
