Depending on the cactus, SWIY's 300mg may have only contained up to 150mg mesc. Thats a fairly low dose, especially if SWIY isnt sensitive to Mescaline.

Double it next time and take it on an empty stomach

how so? i thought that this tek produces around 85-95% pure. It was from San Pedro supplied by HP.

From SWIMS own experience with these teks and specifically san pedro, the alkaloid mix that gets pulled is about 50/50. Obviously this varies from plant to plant, but most of SWIMS Pachanoi's yielded %50 Mesc and %50 other various alkaloids. These alkaloids are quite different to Mescaline

I seem to be only getting small 30 mg yeilds each time, with both seltzer water and vinegar. What do you think could be the problem? I let the limonene soak over night and shook up the seltzer/vinegar with the limonene thouroughly (3 times with settling breaks in between). Id really like to scrape up a nice couple hundred mgs atleast once. Can someone help me?

First of all, seltzer water isn't needed for this tek, just use tap water.

Where did you get your cactus from? Was it dried chips or have you harvested it yourself? If you got chips there is no way of knowing what they are. If your other ingredients are all good quality then perhaps you hav been sold bunk cactus

I got powdered Peruvian torch from icaroDNA I was told by some other members that its a reliable source.

Perhaps your vinegar or limonene arent good enough then.... I doubt that its the way you are performing the extraction, its a very simple process, so it must be one of your ingredients.

What was your % yield?

From what SWIM understands, the vinegar pulls should be done on the limonene before the seltzer pulls. If you've saved all your materials, try doing another limo soak and try pulling more from the limonene until it stops producing yield. Double check to make sure all your ingredients are correct and used in the proper proportions.

The order in which the pulls are done doesn't matter. I was able to get very clean acetate off of limonene after 4 pulls with soda water yielded nothing (though it did fog up the limonene).

Icaro has given me straight 1.4-1.5% yields

It was SWIM's understanding that some of the acetic acid was absorbed into the limonene, which is why some people have reported that doing only carbonate pulls has been ineffective. I wonder if anyone has tried adding a bit of dry ice to vinegar?

edit: Testing some used limonene with ph paper shows no reaction.

This could be a tad confusing for those that havnt extracted before or havnt read everything in this thread... Perhaps keep the seltzer water theories to the other thread

I actually think he was right, after my vinegar evaped it appears to have yeilded nicely. (haven't weighed it yet. I had read that after making my post and thought that could have been it. I will try again later with the seltzer to see how it works after the acetate pulls. (sorry for bringing the seltzer to this topic it just seemed mildly relevant.)

My friend got about 300 mg of a goopy, brown substance after the first vinegar pull. The second time, she got about 500 mg of white waxy crystal substance (after second vinegar treatment of the same limonene), much whiter than the tannish crystal she'd gotten from a prior extraction. Both taste bitter, I am told. One presumes that both are active.

Is the brown goop a collection of alkaloids other than mescaline, and the white second draw a more pure mescaline draw? Or does this just sometimes happen,and we can presume that both substances are a collection of alkaloids, both mostly mescaline?

Swims second attempt at this tek.

Same cactus, same harvest, kept frozen until the drying process.

This time the cactus material was sun dried, as were the vinegar pulls, rather than being (in both cases) dried in an open oven.

The yield this time, from the first two vinegar pulls, is ~475mg, from 100g of dried cactus.

I'll have to check back and see but I think that's already a little more than my total yield (half dozen pulls) last time and hopefully the real gain is in the potency.

Will bioassay sometime in the coming weeks to verify.

Kudos again to Ron and big ups to all the psychonauts.

Just wondering, if instead of mixing the cactus and lime together could you dissolve the lime in water and then decant off of the basic water from the powder cations that settle out at the bottom, and then use that hydrate the powdered cactus to a doughy consistency.

Not sure that would work b/c the small amount of water needed to hydrate the cactus will not be enough to fully dissolve the lime. I use well under the 300ml, just enough to get it wet.

SWIM bioassayed ~150mg last week. It does not seem that acetates are very heat sensitive, since one of the pulls was partially dried in an oven at ~200F, and the others with a hair dryer on high. Amazing stuff!

Does anyone know if warming up the d-limo when extracting the mesc from the cactus skin would help absorption of mescaline? Thanks.

I don't think it would matter. I think 95% of the mescaline gets pulled out with the first two limo soaks (as long as you give them 24hrs each and stir often). When I heated my 2nd pull last time I didn't get any more mescaline, but got more goo, so it seems like heating the limo just pulls out more goop.

Interesting, Thank you, much appreciated.
