4-HO-DiPT was a substance I had wanted to try for many years, but I struggled to find it. Once, I was close, but customs seized my order. Recently, however, fortune smiled on me, and I successfully acquired it, adding it to the list of tryptamines I've tried.

I decided to start with 15 mg taken orally.

Noticeable effects indistinguishable from placebo appeared only after an hour, which surprised me. Shulgin wrote that 4-HO-DiPT stands out for its fast onset. My experiences with other tryptamines usually began 20–40 minutes after ingestion, but here, I had to wait a full hour. Before the effects appeared, I was already accepting the idea that I wouldn’t feel anything. Fortunately, I was wrong.

The most noticeable thing at first was that I felt cold - something I typically experience with tryptamines, especially since I was lying still in bed. I knew then that something was starting to happen. This was accompanied by trembling throughout my body, especially in my legs. Surprisingly, I found these full-body tremors pleasant. My body was filled with enjoyable, almost euphoric sensations.

My thinking and reasoning was pretty sober. This was noticeably different compared to tryptamines like shrooms or 4-HO-MiPT. At 15 mg, the mental effects were quite weak. I also didn’t notice any CEVs. OEVs were present - shroom-like, weak, subtle but noticeable. They grew more intense over time but never reached a level that would overwhelm me.

The euphoria I felt in my body but not in my mind was the main effect during this experience. Music sounded good but not so good as to draw my attention in any special way.

I decided to go outside and take a walk around the city. While walking, I felt as though I was gliding and observing everything around me. I looked around and could closely examine everything. The trees were beautiful, and it was easy to notice the patterns formed by their branches.

As I was walking, I felt a light dissociation, probably because my usual perception of daily walks suddenly felt entirely different. I paid attention to details - everything was interesting. I passed a man with an unusual way of walking, or at least that's how it seemed to me - I noticed it more than I would have if I were sober. It looked grotesque, strange, different. Everything seemed like a parody of reality.

I ended up in a busy part of the city and began hearing sounds beyond my headphones. I took them off and heard a terrible cacophony from which I couldn't make out any specific sounds. I couldn't tell if I was hearing music from a nearby bar or conversations of people behind me. I just heard a formless noise. It was probably overlapping conversations mixed with distant music, but I perceived it as something interconnected. It was clear that my perception of sound was altered, but I didn't experience pitch lowering like with N,N-DiPT or 5-MeO-DiPT. Instead, there were changes in how I mentally processed surrounding sounds. The street noise stressed me out.

I entered a shopping mall, mainly because I wanted to see how 4-HO-DiPT would manifest in such an environment. I took off my headphones again and experienced the same thing - total noise, from which nothing could be identified. I heard only a brutal chaos that seemed to pierce my brain.

I entered a grocery store inside the mall but wasn't planning on making any major purchases because my social anxiety was kicking in. I wondered if I could handle interacting with the cashier, but I decided I could. Beforehand, I rehearsed my lines in my head several times: "By card, please" I managed, but when I said those words to the cashier, I didn't recognize my own voice, and I thought I might be experiencing pitch lowering like with N,N-DiPT. However, later tests with familiar sounds didn’t confirm this effect. Apparently, it’s something else - definitely altered sound perception, but it seems to be more on the psychological level rather than directly affecting pitch like N,N-DiPT does.

I returned home listening to music on my headphones. It was a pleasant, shroom-like walk but without any deep reflections on the meaning of life.

I took the substance at 5:00 PM, effects appeared at 6:00 PM, and by 8:00 PM, the experience was over, except of some subtle afterglow.

To summarize, what I found characteristic of this experience, compared to other 4-substituted tryptamines, was the bodily euphoria, chills unrelated to perceived temperature, a sober mindspace, mild visuals, pleasant music perception, and altered sound perception, particularly of street noise.
