This occurred at home, and it was late evening Sebastian took the sample of 5-MeO-TMT from the bag, and weighed out approx 90mg and swallowed it. He had heard about this place in a book written by a wizened old man. An ancient tome filled with the never ending story, every dream imaginable in every land.

5-MEO-TMT, one of Shulgin's lesser known creations. A psychedelic tryptamine little heard of outside of TiHKaL with very little known information about its effects on humans. May be particularly given to causing nausea.
