MA-6, 2,4,6-trimethoxyamphetaminI noticed from earlier tests that TMA-6 has quite a pronounced vasoconstrictive effect, so for this reason I took but a small dose - 10 mg, whereas Shulgin recommends 25-50mg. This was a test of a new psychedelic (effects, physical tolerability) more so than it was a trip for the journey's sake. Taste of the off-white powder was quite chemical.
