Why is FASA advantageous?

What exactly are the primary benefits of using the FASA/Xylene method over the normal STB method with Naptha? I had a lot of success before using the traditional Naptha/Lye method. I got it to a point where I was getting glistening white crystals through simple (very simple) freeze precipitation after evaporating the pulls down to a minimum.

If I'm not mistaken, the FASA method offers two things:

1) You can re-use your solvent (Xylene) because you dont have to evaporate it down, but rather use FASA to crash out the alkaloids over and over then re-add the solvent for further pulls.

2) You know when your material is devoid of alkaloids because no salts crash out of the solvent when FASA is added.

3) You dont need to freeze precipitate.

It doesn't save time really, because you have to evaporate the acetone after the acetone wash, and convert the salt to freebase if you want to have a smokeable product. Even then, if you want pure white DMT product, it is recommended that you still pull your fumarates with Naptha to get the alkaloids out only.

So it seems like it adds a few extra steps and doesn't really offer much advantage.

Am I wrong? I'm just trying to learn, not trying to sound critical. I only know my way, and am very open minded =)
 
yields are far better if one pulls with xylene (and then go FASA) or i fone pulls with limonene (and then goes FASI) because both solvents can pull tons when naphtha pulls yield no more. SWIM get at around 1% yield wit hnaphtha but this can be pushed up to 2% if xylene is used.

Other than that, xylene and limo allegedldy pull more alkaloids like n-oxide and "jungle".

It may take more time but that is irrelevant. I cannot really understand why one would like to extract the spice in the quickest way possible. SWIM is not in a hurry and loves taking his time when he can.
 
Well, I was just curious. I'm not against spending time on the project. I find it fun - I just wasn't aware what the advantages are. I'd have probably tried it just to have fun crashing goodies out with FASA in a dramatic way. Heh!

So you're saying Xylene pulls more pure alkaloids too? Or is that other 1% jungle stuff? Because in some of the guides it is said that if you want pure white DMT without the jungle stuff, you have to pull the freebase with Naptha, which kind of goes right back to square one (seems to be pointless to do all that just to re-extract with Naptha).
 
If you pull with xylene and salt out with fasa, the fumarates are much more pure than if you pull with limo and salt with fasi. Has anyone else noticed this?

Yeah that's what I think. But that said, impurities from limonene are going to be less toxic than impurities from xylene.
 
The shelf of of the fumarate is much longer vs standard freebase. FASI yields were very good for SWIMS first time. Around the 8.6g mark.

Around 6.4g or so mark after freebase conversion. This was on a lb of shredded bark.

And they are much more fullrange. The vaped experience can get quite wild at times but has a much "fuller" aspect to it.

And fumarate seems to do very well in the absorbing process of the stomach. SWIM always uses a cap with a hole poked in it. Works excellent.

Peace friend~ :)
 
Mumbles, that's true, but DMT N-Oxide has effects that are different. SWIM prefers it over DMT. But it's sticky and hard to work with.

I think the stability of the fumarate is overstated. The degradation product of dmt is just as active so...

This is true; I have not seen anyone doing a proper analytical and controlled study on the stability of fumarates vs freebase or other salts.

The alleged stability of the fumarate is based (to some extent) to its ability to dry. Presence of water (as in the other hydroscopic salts of dmt) can lower shelf-life of may compounds. But yeah, for the most of the time it is an alleged-rumour-turned-fact. But this is not too far-fetched.

As for "degradation" we also do not know much; "degradation" can be n-oxide formation and this does happen over time esp in freebase stored at room temperature over long periods of time. But molecules can literally degrade over time to other byproducts for which we have no idea of what they are, how they look like or whether they are active.
 
1 Answer: You'll see! Watch this video!

but to answer your question, from my point of view whether you do STB, A/B or a BLAB style FASW crash, they're all equally as good.

All of the teks are pretty simple, all of them take time, and all of them produce DMT.
You're looking at it and thinking what will get me some DMT in as quick a time as possible?

but look at it another way, some people love spending time on the hobby side; extracting
lots of different ways and testing/inventing new methods of extraction, purification and dosing!
