Hi Nexians,

I have a San Pedro growing in a window on the south. Been growing for several years now.

I want to know wether I have enough for a worthwhile Mescaline-experience, without cutting it up and weighing it.
I also wish to leave the bottom and top 5 cm untouched so they can both regrow into new SP cacti.

Is there a way to determine/estimate the Mescaline content of my SP by the length & diameter of it?

Each clone, and even each plant depending on conditions, can vary so wildly in content. The only way to know is to either eat it or extract it and weigh the extract. Some plants will give nothing from 24 inches and others will make things interesting with 6 inches of material.

PS 5cm is a pretty small bit to recover. I think you will find it gets stunted and grows back pretty slow and thin. I like to keep my cuttings for planting over 6 inch ( ~ 14 cm?) and the larger the faster they grow back.

Good luck !

good advice

Hmm I wouldn't like to accidentally take a rediculously high dose of Mescaline on my first time.
Seems extracting it is the way to go if one wants to be able to control the dose carefully.

The advice given is sound. I would extract it. Pure-ish mesc is awesome. Plus you will get absolute confirmatioon the potency. (assuming you do it right)

If extracting isn't in the cards... Eat a foot long piece, prepared however you like. That's really the only way to know.

Well, don't go eating 2-3 feet of cacti but.... I think a foot is a safe bet. Maybe half at a time if you are worried.

Eat a piece of the green flesh.... If it's really bitter, it may be strong.... If it's not bitter, it's probably very weak.

Thanks for all the advice. SWIM thinks he'll go with an extraction, since he's not too unfamiliar with STB DMT extractions from MHRB.
SWIM hopes this extraction can be done with solvents he can obtain. SWIM's never seen Toluene or D-limonene sold anywhere in his country.
SWIM can get Acetone, Diethyl Ether, Petroleum Ether, Naphtha and Ethanol, but wouldn't know where to get Toluene, Xylene or D-limonene.

where did the cactus come from?
how was it identified?

how thick is it?
how long is it?

weight can be estimated by volume

Yeah a foot is a pretty good starting point. Although I have 2 cacti that are very active and the effects from 1 foot of either of them seems to be almost double that of my others.

Mescaline is quite forgiving though so don't stress too much about it. Just lop off a foot and see what happens.

Happy travels

Because my Cat has never done Mescaline before he feels an extraction is best in order to be able to dose carefully.

My Cat thusfar has only seen extractions including Xylene and Toluene; 2 solvents not commonly sold around here. He doesn't even know if they're available in his country.
My Cat can get Acetone, Di Ethyl Ether, Petroleum Ether, Naphtha and maybe IPA. Can Mescaline be exctracted with any of those?

All my attempts at extracting mescaline have been with xylene. I tried a crude tar extraction with IPA but that was pretty bunk.

I'd look into it though, sure there is someone out there who has used the chems you have available.

Thx PrimalWisdom,

So this Mescaline extraction was done with Xylene as the only solvent? Can you link me to this extraction Tek?

Also another thing that became appearant is that it's really hard to find solid reports of the average Mescaline content of San Pedro cacti.
I have various sources stating various percentages(Concerning fresh cactus): 0.12% of it's weight(Shultes & Hofmann), between 0.21 and 1.8% of it's weight(Wikipedia),
between 0.05 and 0.075% of it's weight(Another source I can't identify)

An average of those percentagge-numbers is 0.451%. Can anyone with mescaline extraction verify this percentage?

yes, i already asked the info i need
here it is again:

where did the cactus come from?
how was it identified?

how thick is it?
how long is it?


simple stuff,
you likely have the PC clone,
that is about 0.15% mescaline dry or 0.01% wet weight
here is a paper with different test results collated into a single source:

eat all of it minus what you want to grow, thats the only way to know if it was worth it...

if you dont want to........ send it to me, ill let you know how it went

Albert:

My San Pedro was ordered from a Dutch smartshop. So far they've allways delivered good products and gave good service, allthough they are rather pricey.
I've been growing it now for about +/- 5 years now. I would be very surprised if it turned out they sold me anything other than Trichocereus Pachanoi.

So according to those percentages you mention the smartshop's dosage indication for San Pedro was about right: That you'll need roughly 400 grams of dried cactus to yield roughly 400 miligrams of mescaline; a proper dose I understand, good for an experience in between +2 and +4( Shulgin Scale)

Thusfar I've had no luck finding Xylene (or Toluene) in the Netherlands (any suggestions as to where I might find it round here, anyone?)

It seems I'm going to need at least Xylene for a mesclaine extraction, and possibly Toluene too, so untill I can obtain those solvents I think I'm just going to take a shot in the dark,
brewing San Pedro Tea. I might drink half of the tea first and then wait 2 hours. If desirable I might take half of what is left of the Tea. And so on.

I'll report back to let you know how it went, might I decide to do it.

I'm sure you mean 40grams of dry and 400 grams of wet cactus?
