you have to know what strains to eat. hypothetically of course, and for educational purposes only, not for ingestion. because any actual ingestion of LSA through seeds or otherwise would be illegal without a prescription. Lysergic acid amide is a schedule 3 drug that is prescribed as a vericose constricter. it is hallucinogenic at higher doses but you need to understand that to prepare it for ingestion from seeds would be illegal.
having said that, the "literature" and "anecdotal accounts" recomend (in order of potency from least to strongest):
1 heavenly blue
2 flying saucers
3 pearly gates
star of yelta is another but I have yet to find a good breakdown of its content.
hypothetically if the seeds were to be utilized by a maztec shaman, they were ground (about 300 seeds per 150lbs) into fine powder and soaked into just enough water to hydrate them. then they would be eaten. followed by nausea and hallucinations for 4-8 hours.
do not use "tall mixed colours"
no LSA content
again this is illegal and too much vein constricting drugs will artificially induce gangreen symptoms in the outer extremities. safe cieling for a 150 lb man is 600 seeds and thats pushing it. I do not condone or take part in drugs or any other illegal activities nor have I ever ever ever done anything that illegal so you shouldent either.
