In descending order:
1) 4-aco-mipt (sooooo pleasurable yet insightful)
2) 4-ho-dmt (i have yet to try a high dose, but I enjoy low doses a lot)
3) 4-aco-dipt (a deep, mature psychedelic)
4) 4-ho-mipt (a bit tweaky, jittery but nice)
5) 4-aco-dmt (have yet to really develop a liking for it but this might still happen)
6) 4-ho-met (my one and only trial was a bit, well, okay... will try again but it was nothing special... I never pleateaued properly and felt restless for along time, though set may have played a key role)
Haven't tried 4-aco-det and 4-ho-dipt yet, though one day I will. Any others I have not had a chance to encounter because no one has been nice enough to say "Hey man, try this!"
4-subbed tryptamines are, on the whole, my favourite tryptamines. And I do prefer tryptamines to phenethylamines, on the whole, as well.
Yes, indeed... sparkle on

edit. oh yeah, I have also had 4-MeO-MIPT... clearly a lot "weaker" than all the others, subtler in any case. A different kettle of fish altogether. Nice and would happily ingest again but I wouldn't go spend money on it again.
