What is in your opinion most deep and profound and even positively life changing psys? So far I'd say 4-ho-met, because it made change my life style much more healthy way, exercising, stopped smoking, etc.
i'm assuming you've tried the other basic psychs or many of them (acid, shrooms, mescaline, ayahuasca), correct?
anyway, it's funny, cuz for me 4-ho-met was one of the least profound psychedelic i've tried. not lacking profundity 100% but far from many of the others.... i guess everyone responds somewhat differently to each one.
