Also short for
2,4,5-Trimethoxyamphetamine.
From personal experience (40mg and 30mg): I've tried this compound twice. This stuff takes it's time coming on and lasts forever. I've found there's not a lot of introspection with this stuff, or for that matter, paranoia - it felt a bit like the drunk version of LSD... I enjoyed it :) but then whatever gets you through the night.
