A/B cleaner than STB? which method seems to provide the most pure DMT, and least 'jungle crap' stuff?

I have a little bark and I'm wondering if i should just stick to 'safe' A/B? does STB come out less pure?

It depends on what bark you're using; for MHRB clean STB results can be had by keeping both the temperature down (20-40°C) and the extraction time short. Some more thorough investigation appears to show that most coloration arises through polymerisation due to prolonged contact with strong base, at least in the case of MHRB. Other barks (and acacia phyllodes) respond better to A/B extraction as they contain additional components which can contribute to an oilier product.

In your opinion what is a good compromise between short enough to minimize polymerisation, and long enough to 'break down the bark' with lye? I think that's the main benefit of A/B is to process the bark as much as possible before basification so you can minimize the base time.

The polymer explanation still confuses me though. Can you run through how alkaline aqueous conditions are catalyzing the polymerisation? Is the solution still supposed to be re-dissolving in acid to break the polymers? Because that hasn't changed the color in my experience; of the solutions or the precipitates.

You can get a best of both worlds situation by doing an acidic soak with a few freeze thaw cycles before doing STB.
Then you can pull immediately for a clean first batch then let the base soak for a few hours to pull more.

MHRB, and I used to do A/B and then 'clean' or get it super pure with heptane. After some point, i became ultra sensitive to any of those jungle spice alkaloids.

Most people will not even notice those jungle/crap compounds in most spice but if there is any of it, it ruins the trip for me. Ugly colors, horrible feelings, none of the intense contrast, digital cartoon or flat polygon visuals that pure DMT will give me.

So I will probably just do A/B since I have everything - years ago I used to not bother checking the ph, just would dump straight HCl liquid in, dump powder NaOH in randomly, it worked fine until the bark got worse quality. So I guess I will just keep the ph within sane ranges. I have heptane, and i bought non-powdered bark just the straight plain bark since it seems like that would be more likely to be better.

I was wondering if its feasable to separate DMT using column separation - I have never looked into if that is just not worth doing or if the amount is too small.
