    Summary dose.wiki Erowid TripSit PsychonautWiki

    4-AcO-DiPT is thought to act as a prodrug to 4-HO-DiPT (Iprocin). It is available in both freebase and HCl salt forms, with the freebase being approximately 10% more potent by weight. This substance is characterized by atypically strong physical euphoria and sensuality with minimal visual effects, distinguishing it from most other 4-substituted tryptamines.

    Effects Erowid

    Aggregated from 32 single-substance Erowid experience reports; 15 Erowid reports where another drug was taken too are left out

    Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

    Also reported in combinations. In the 15 4-AcO-DiPT reports where another drug was taken too, 4 mention hospital, emergency services or an overdose, 1 a seizure and 0 psychosis (too few reports for percentages). In the 32 single-substance reports: 9.4%, 0.0% and 0.0%. These are not in the figures above: they cannot be put down to 4-AcO-DiPT alone, and a mention is not always something that happened to the writer.

    On the Mountain Trail positive exp #54933

    I just thought I'd share a beautiful/funny/terribly frightening experience on 4-aco-dipt. Tripping in nature is great but it can bite me in the ass if Iย’m not careful. My girlfriend and I set up our tent in the mountains on the Appalachian Trail. This seemed like the absolute perfect setting.

    An Intense but Fabulous Trip positive exp #38362

    This was my highest dose so far of this delightful chemical, and very interesting. As is usual for me I had a whole day clear for the experience, with an easy day following to cope with any after effects. I was alone in my flat, with no worries about anybody intruding, and generally in a positive state of mind.

    The setting: 8 pm, Saturday, in a comfortable, safe, spacious apartment. Five people were present, four of whom were interested in exploring this new compound. J, male, was quite experienced with psychedelic materials, particularly psilocybe mushrooms.

    On the day in question, tripping was the farthest thing from my mind. I had spent afternoon walleye fishing at a local lake, drank a few beers and smoked a joint while I was out. As the sun was beginning to set, my friend B showed up and wanted to know if I was down to trip.

    Introduction (those not interested can skip this part): I work as an healthcare provider in an institution for brain-damaged people. This might influence this report in a neuro-psychiatric direction, althought not intended to be exhaustive.

    Beyond the Beyond positive exp #18856

    There is a time and a place for everything ... having possibly the worst month of your life and being in a terribly state of mind is not the time to be doing extremely titanic amounts of drugs. Its childish and irresponsible, pure and simple, but it was what I was desiring as a method of release and escape.

    On a 'Blind Date' neutral exp #28697

    After experimenting heavily with AMT, I decided to broaden my horizons a bit and try something new. 4-Acetoxy-DiPT was brought to my attention, and I procured about 500 mg to play around with. However, I do NOT give any substances to friends without trying it myself first, so I put myself into my bedroom.

    5-Day Binge neutral exp #34653

    Abstract: A five-day Ipracetyl binge is experienced with no evidence of tolerance. Little in the way of side effects are encountered, although a serotonin-depletion type hangover occurs at the end. The higher dose range is associated with open eye visuals.
