There is one thing I don't understand about LSD. From what I have Read from Ray Peat LSD is named antiserotonergic substance. But in other places like Wikipedia or medical articles on pubmed there is info that LSD psychodelic properties comes mainly from 5-HT2 agonism, not antagonizm. 5-HT2a antagonist blocked psychodelic effects from LSD. I know 5-HT2a agonism releases dopamine so thats propably why it's halucinogenic. So it's more serotonin agonist, not antagonist like cyproheptadine.
