The San Pedro is coming my way next week! :D So ofcourse I have a few basic questions since I find multiple sources stating multiple things like different dosages etc.
1 - Is it true that the amount of Mescaline in a San Pedro cactus can vary a lot?
2 - What is the best preparation method? I heard something about boiling in water for about 2 hours but don't know if it's the best method.
3 - What is the recommended dosage for a 55 kg / 173 cm first time tripper? (only had LSA and Salvia 5x before)
4 - Can I expect a visual trip only or does it contain a mindf*ck also? I am really looking forward to seeing some visuals but don't care a lot about my thoughts while tripping since meditation helps me clear my mind
Sorry for all these (maybe obvious) questions, but I'm sure someone here has enough knowledge to answer some of these questions or can provide some links with reliable information.

Thanks in advantage
Thought about posting it in the mescaline thread, but since it's my first real trip on something like mescaline (with visuals etc.) having good information and knowing what to expect can reduce the chance of a bad trip. My set and setting will be good with some goa/psy trance, lots of weed and a few diazepams to help me with the comeup.

(I'm always pretty nervous when trying something for the first time so I always take 10-20 mg of Diazepam to help calm the nerves)
Peace o/
