Greetings once again :] I am back with mooooore questions!

I have been unable to find anything regarding dosage for San Pedro cactus powder.

22" of San Pedro, one 11" piece 4" in diameter and one 11" piece 3" in diameter, were skinned and the cores were taken out, then they were blended and cooked for many hours. They were then placed in front of a space heater until completely dry, and then ground down in a coffee grinder to a fine powder.

176.5g of powder was acquired from 22" of San Pedro. I was just wondering, how much mescaline could the powder contain? Should one consume all 176.5g or only 50g like everyone says on the internet? I have only ever had the tea, which was from 14" of cactus and it was strained... all plant matter was discarded. So I'm assuming that ingesting 22" of cactus, plant matter and all, is going to be a much, much stronger experience?

It would be impossible for someone to day "x inches of cutting will have x mg of mescaline in it", because alkaloid content varies tremendously. Especially with pachanoi. There are a lot of factors that play into this.

Honestly, there could be >5 doses worth of mescaline in your cactus powder. There could also be zero doses worth of mescaline in your cactus powder. The best way to go about it would be to either extract the mescaline, or to start with a small amount and work your way up if necessary.

I see. So, starting at 50-60g and re-dosing every hour - hour 1/2 would be my best bet?

Mescaline is notorious for sneaking up on people, a.k.a. requiring much longer to take effect than the person expected. An hour might not be long enough. I have heard more than one report of a person not feeling any effect from cactus until almost 3 hours after ingestion. But if you were to take 50-60g every three hours, you could very well end up having a very mild experience that lasts ~36 hours.

What I meant by "work your way up" is that I would take ~50g and then not take any more that day, to determine how pronounced the effects of ~50g are or if it has any effect at all. If ~50g produces significant effects, then you'll have more left for your next couple experiences. If you feel no effect whatsoever then I would wait at least a few days to a week, to avoid building a tolerance, and then take 100-125g on another occasion.
