So I have acquired 4 12 sections of San pedro about 3 inch thick off what looks to be an older/larger cactus. I was thinking of using a few different prep methods as I will have about a week to prepare. Was going to use the freeze method then boil in crock pot as my stove is electric and harder to control temp. The 4 pieces will be split between 2 people. I have quite a lot of experience with many psychedelics though it has been over 10 years since the last trip, but never had mescaline. The other person is a complete newbie and never used psychedelics at all. I know cactus varries a lot. I am just looking for opinions and advice on the prep and amount. Do you think this will be enough for a good solid trip with decent visuals? If I may need more I can acquire fairly easy but need to figure out soon to have enough time for prep as it seems time consuming.
