Well I've been dying to try this since the days before webtryp, and I finally got myself a hold of a 50mg sample, which I took.
Effects lasted for approx 4 hours, so it's not as long or as pronounced as the 5meo or 4- cousins.
I'd heard about the so called "intellectual stimulation" that this drug affords, so I was interested mainly for that reason, and to test my theory that in high enough doses it would prove to be quite hallucinogenic.
Time to come on was about 20mins-usual by oral route on empty stomach.
Peaks around 1hr - 2 hours. Spatial distortion very evident - things like doors and tables appear "shrunken" but the rooms and interior of the house seem massive, like my house just doubled in size. This was an interesting effect.
Mild hallucinations and perceptual distortions, all visual, noticed, but nothing particularly colourful. No desire to listen to music, but if I did I doubt I would have experienced any enhancement. No desire for sex or tactile bliss.
Overall, a type of "retarded" feeling to the action of the drug on the receptor, as if the IP group is having trouble dissociating and so not as frenetic as a dimethyl, methylethyl or diethyl. In this case a very similar feeling overall to 4-aco MiPt, and not at all like 5meoMiPT (which when I took it found quite overwhelmingly speedy).
I've decided I don't like the methylisopropyl moeity much. Instead of intellectual stimulation, which I expected to enjoy in the post-peak period of 3-5 hour mark, all I found was a distinct "sluggishness". That one word really captures the overall feeling quite well. Sort of a lazy, slightly soperific and depressogenic feeling just wanted me to go to bed and stop experiencing the drug. So much for feeling stimulated!
I ended up terminating the trip by taking zopiclone etc and going the heck to bed.
I won't be repeating experiments with this one, overall very disappointing considering the build-up I had formed of it in my own mind. I think that experiments with 125mg could really bring on the visual psychedelic aspects of this drug, but I personally don't want to experience that sluggish iP terminus feeling again, especially at double the dose.
If you want intellectual stimulation look elsewhere, this is about as stimulating as taking rauwolfia root.
