A friend of mine is planning on doing a mesc. extraction.
He wants to do it with 69ron tek, hcl and acetate extraction.
But he has a few questions:
What kind of cactus should he buy: achuma or san pedro?
Does anybody know a real good vendor for potent cuttings in the eu?
How tall shoul the cuttings be?
Thx

If you're asking how tall the cuttings need to be, you need to look around a bit more. IMO. The answer is up to you, how hard you wanna trip. Doses and how much mescaline is in cactus is easy info. Generally .5-2% a safe bet, but as low as .3 and high as 5% Who knows?

For an extraction, san pedro is usually preferred over bridgesii, (but bridgesii is awesome monkey fuel too) Usually 1 ft of san pedro will get someone to a light level of tripping. This could vary greatly though, some cuttings are barely more than an inch wide, some are 3.5 and bigger.

You are gonna need to dry the flesh if you plan to use that tek. I have nothing against that tek, haven't tried it yet, but good ol mesc hcl is EZ too + has a history.

Cut up your cuttings, cut out the core, shit there's a great picture tek I think in the cacti section, can't find ATM. You wanna get strips of green flesh dried ideally, then ground that shit, then do your tek. The more mescaline the better, I doubt you will buy too many cuttings. Get 4 or way more feet and start cutting and drying. Have fun.

Edit: whoa, you don't do hcl AND acetate extraction, (unless you mean do both?) see those are both acids, you only need one to get the mescaline. Alternately you can use sulfuric acid. Amount needed will vary.

Read the tek, see the tek, make the tek happen, no variations the first time right?

Thanks for answering
No i mean to do both types of extraction to see/feel the differences .
Do you know a legit eu vendor?

I've seen a few mentioned, look in the supplier forum in the Arts and Cultures sections.

Cool do both, that's kickass man, let us know how it goes. Take time and do it right. If I were to do both I'd want at least 4 cuttings in each, probably more. P. Torch is usually the choice cactus for extracts I believe.

What solvent are you using?

I have found using toluene instead of D-limonene for Hcl yields a very clean mescaline powder without even doing the acetone cleanup step. Its up to you what you use but IME I'd rather get white powder with less effort.

Than i think toluene will be the solvent of choice..

riverssourcebotanicals.com is a good one that i can vouch for. i'm sure they ship to europe. they have dried t. bridgesii skins and SWIM found that 100 grams of dried t. bridgesii skins was one weak dose.

Hmm, according to my knowledge, 100g of dried bridgesii skins should be awesome experience. I estimate about 5% dry weight from wet, so 100g = 2000g fresh cactus.

edit : well here's something might helpTrichocereus Dry Weight

Toluene yielded a very clean first pull for me, about 300mg of sparkly white with hint of tan/pink, from 32 inches (roughly 1900-2100g fresh) of bridgesii cactus in a tea based with lye. Other pulls were much less clean but I attribute that to less than satisfactory working equipment. Better siphoning and more suitable jars would have helped to make sure pulls were cleaner.

I hear if you use the 69ron tek a french press makes the process much easier.
