AB vs STB

[Mortirius]

I have a simple question.à
When using mhrb can someone list the pros and cons of using a ab vs a stb tek
I've looked through the forum but I cant get a straight answer.
I know the ab is a little bit harder with a few more steps.
So taking that onto consideration here's the question.
Using mhrb with naptha as the solvent and isohexane for a rinse. What is the advantage on the final product of going with a an ab rather than a stb?
Thank you for you're replies.
I'd love to hear from someone who has done both with the same mhrb stash.

ab stb site:www.dmt-nexus.me - Recherche Google

I think there is a lot of info about that. Are you sure those links are not answering your question?

I actually read all of those but there's no straight answer. People are posting contradiction to what others post so I'm left still a little confused. However what I'm left to conclude is that stb might yield some plant oil causing a little yellowish waxy spice but after an isohexNe rinse it should be cleaner than an AB. (I'm assuming). There's no posts on that. Also the closest post that has the pictures says he used a different source for each Tek so that's not valid imo. If someone has the information from experience I'd appreciate it if they replied. Nontheless I've done only the STB no rinse and I can say it produced some yellowish white with a little waxy crystals. without a doubt after trying it that I saw 100s of jesters faces inside a some sort of long snake like tube smiling at me. (similar to my avatar). I'm taking from it that I maybe joke around too much with people so I'm going to try and reduce that. Overall a positive exp. It was my first time and I've done four times after with not so similar results I think I didn't smoke enough the latter times because of preflight anxiety. I'm going to do an AB Tek and repost my results and exp in the upcoming month or so.

STB can produce yellow dmt, but the same is true for A/B. It all depends on the procedure and solvents used. I prefer STB, but mainly because my bark is compatible with it and it is not causing emulsions. The color of the extraction result is not as important, as simple re-x can provide very nice white dmt from most extraction results and the remaining yellow fraction is still very nice, so in fact there is no yield loss.
The most important imho is the bark. Some barks seem to be good for STB, some not. If any emulsion happens, then it may be reason to try A/B. And vice versa.
If there is no emulsion, then the result is likely to be the same, when both STB an A/B are done properly.

It depends on you and your aim and your preferences.

STB is great for small amount and is easy because it doesnt require you to cook anything, you can just do it in your own time and come back to it as you please. Troubles with this? Emulsions are a big one, especially with powdered bark, effectively it is just one big homogenized soup that can be as thick as slurry. Shaking the jar over rolling it could be a no-no depending on your set up.

Acid/Base is better for bigger extractions (say if your alkaloid content in bark/leaves is only 0.1%), why is it better? Simply because you can cook a lot by volume and reduce however many liters to a workable size. What problems are there with reducing though? Well if you don't filter properly before basing then you will run in to emulsions because as you increase cooks you increase tannins which furthers emulsion troubles. Another issue is you could mess up the cook stage by not having enough acid (to form dmt-acetate), or not having powdered/shredded enough material, or not cooking long enough.

Ive always preferred AB because the solution is always thinner and easier to work with, I feel more in control with respect to emulsions.

My last A/B was many years back, but I remember I used to have problems with emulsions too. But I was filtering just with t-shirt, so maybe some proper filtration migh mitigate them.

OP was asking about MHRB, so I would suppose his bark is >= 1%. One 5l bottle can do 250g of bark and with proper ratios (1:15) it is far from thick. Compared to cacti it is just a water The result would be 2,5g of light and for good bark much more, my bark has always > 2.5%. Definitely no reason to need bigger extraction if not producing commercially. But nobody does that here, right? But yes, for some other source material with lower content, A/B might be better.
