As the year of 2025 came to a close, and as it has been a rather terrible year in one of my friend groups, and I too have had to overcome various hardships, we came up with the idea of a celebration party towards the end of the year, to celebrate the fact that we still have each other, and the fact that we made it through this abomination of a year. At the same time, really, we also all wanted to do substances together anyway, so this seemed like the perfect excuse for the whole group. As such, everyone prepared whatever substances they felt like taking, which meant a wide range of different substances were had.

As someone who likes to take various psychoactives, with my current focus on tryptamines, I had a bit of recently-synthesized 4-PrO-DMT laying around, a substance which I hadn't taken before. I made sure to have it chemically analyzed beforehand to make sure that this was indeed the substance I was taking, and not some other tryptamine.

I had considered taking another tryptamine already known to me instead, but I decided to go into new territory for this experience, especially since I wasn't otherwise considering this one.

As for medication I'm on, something I did not mention in my last experience report: Nothing particularly noteworthy, only a regular, subcutaneous injection of an estrogen ester, of which the dosage and precise ester shall remain unnamed.

I brought along two capsules of ginger powder (600 mg per capsule), as usual, to counter the very likely come-up nausea. The main substance was repeatedly weighed to be exactly 20 mg.

On 4-PrO-DMT itself, information online was rather scarce, however, Wikipedia, various Reddit threads and three Erowid reports had some useful information that I used to estimate some dosage and time duration information that I've noted down in my notes as follows (for oral intake only). Note that this information is incomplete! It is only what I went off of here!

| Dosage | Dose |
| --------- | ------------- |
| Threshold | 5 mg |
| Light | 5 mg - 10 mg |
| Common | 10 mg - 25 mg |
| Strong | 25 - 40 mg |
| Heavy | 40 mg + |

| Stage | Duration |
| ------------- | --------------- |
| Total | 3 - 5 hours |
| Onset | 20 - 40 minutes |
| Come up | 30 - 60 minutes |
| Peak | 1 - 2 hours |
| Offset | 1 - 3 hours |
| After effects | unknown |

My mind was still rather busy with preparations for the get-together itself, as I had a part in handling things like sound-proofing the windows. But I tried to chill a little before the onset.

I specifically prepared a note on my phone to write down my raw experience, to later merge into a document for my personal experience report vault.

T-2:00: I eat one capsule of ginger powder, equivalent to 600 mg.

T+0: Intake of a capsule with 20 mg of 4-PrO-DMT, along with another 600 mg capsule of ginger powder, with a slight bit of burn (similar to acid reflux burn) still from the initial ginger intake.

T+0:10: I notice my usual visual static becoming slightly more colorful. Possibly placebo?

T+0:15: Some slight incoherence differentiating the colors around. Like a bit of a delay. Still unsure if placebo.

T+0:22: Onset is surely there now. Some discomfort is felt, I have a hard time forming words right now.

T+0:25: Some body high is setting in, and some euphoria. It feels great. My body, or rather my sense of touch, is tingling. Colors, however, are still completely fine.

T+0:30: I feel a strong compulsion to sway to the music that's playing. It is hard to type this text. The environment shifts a bit, but exactly how is not apparent. I jumble my words. My color vision isn't really changing perception-wise.

T+0:40: My vision is starting to change. Not color-wise, but a triangular pattern is starting to emerge. This happens for closed-eye visuals, too.

T+0:47: Time dilation seems to have hit, because my sense of time no longer matches up with the time that's displayed on my watch.

T+0:48: Visuals are starting to be less triangular. They're becoming more soft, and circular. Closed-eye, they are reminiscent of what I'd call "hypnosis patterns", where black-and-white spiral patterns are mapped onto a sort of wall in a spherical room, with a pillar of the same pattern emerging in the center of the room. The black-and-white patterning does not have distinct borders, but rather, they're a bit blurry. Open-eye visuals simply consist of wavy line patterns instead of triangular ones now.

T+0:55: My room perception is changed. It feels as if everything is fluid, and people have a sort of distinct bubble surrounding them that I can enter and leave at will, but I am not part of others, and everybody remains separate. This is different to some other tryptamines (mostly Methylethyltryptamines), where I'd usually feel as if I'm fully part of my environment, and where I can enter crowds of people and be part of them. Bodily, I seem to vibrate a lot, almost like shivering, but I'm not cold. My hands are cold right now, indicating some vasoconstriction, and my forehead is slightly warmer according to someone else. [Post-trip note: This was not rechecked, unfortunately, so I don't know if this went away during the trip still, or if it only went away after the trip]. Colors are still normal, and I assume they will be for the rest of this trip.

T+1:07: Spiral patterns in everything visually (open- and closed-eye), but _not_ infinitely fractalized, they have a sort of limit to them?

T+1:28: I am very comfortable. I don't get to finish typing this sentence. [Post-trip note: I was cuddling with someone. I also had the distinct thought of that being more important than to continue typing.]

T+1:37: There is so much going on in my head. Probably best described afterward. [Post-trip note: Concepts and people were on the mind, and not really in words, but rather, the connections between them, and what they mean to me, were floating in my thoughts. However, none of these was news to me at the time.]

T+2:07: Lots of wavy patterns. Everything has it, but especially around lights. Someone describes my pupils as dinner plates as I type this. I feel warm, and comfortable.

T+2:13: I thought it was later than it was again. I love everyone around me right now. [Post-trip note: Obviously, time dilation was still hitting, and I felt an intense wave of euphoria wash over me.]

T+2:28: While colors seem normal, they appear different. Like, everything has these round patterns around it, and seems different, but I can very much tell what colors are which colors.

T+3:04: Folks around me prepared a pizza with some Cannabis on it. The whole pizza was sprinkled evenly with 0.3 grams of pot. The actual THC content is known to be low, but not known in exact numbers to me. So, I took a piece, which was roughly an eighth of a pizza.

T+3:29: I feel as if the 4-PrO-DMT wearing off. I'm definitely still on it, but it's becoming less of a headspace-heavy effect. Taking a (very noisy) selfie of myself, I seem to have quite dilated pupils still, which I expected.

T+3:56: Everything's rather chill. I estimate this is becoming a sort of flip into a low dose of THC.

T+4:24: I just had a weird thought. It described the moment of the irony of something dawning upon someone, but it wasn't describing a single situation, instead, it was describing the concept, with many examples flooding my mind. This might be the last of the headspace effect making itself known.

T+4:47: Intake of another slice of pizza with weed on it (0.3 grams divided by 8 again). The visuals are fading, and I'm pretty sure they're gone soon.

[Post-trip note: I was busy talking to and cuddling people, so I really did not write much down for a while, but the visuals did indeed fade.]

T+7:03: This time, the pizza "ain't shit". Oh well. Whatever the case, the visuals are gone for a while now. I sure think of THC at the tail end of this tryptamine as a soft landing right now. I am used to the comedown of tryptamines being a rather fast and clear cut shifting of the environment back to normal, but THC made this slower and less "harsh". Anyway, I notice some details on the skin in my face that I didn't before. You know, areas that possibly threaten to become pimples and such. In general, there is a lot of detail in my vision that I didn't really perceive before. I'll see if that persists.

T+7:48: I joined a blunt rotation, since the last piece of the pizza was so weak. Just a single hit was taken.

T+8:40: I feel very disinterested in the prospect of moving. I also briefly had a weird flash in my mind where the corner of the room opposite from the one I was in seemed infested by a lot of insects. Sort of like the drawings of deliriant visuals I saw online at some point. A bit surprising.

T+8:56: Movement disinhibition gone. The group of weed smokers has another go, and so, I join once more, with a single hit. I decided it'll be my final hit for this experience.

T+10:10: Once more, more disinterest in moving. No insects this time.

T+10:20: After a short burst of sleepiness, I am wide awake again.

T+10:40: We've started cleaning up the place, and the last folks still high on something are well into comedown. They still try to help :)

T11:59: Heading home now.

T+12:31: Weird, I fell asleep a bit on the train home. Luckily, woke up a few stops before mine, and felt wide awake again. It's a bit as if my state of being awake or asleep is really binary right now. Anyway, I'll be home soon.

What follows will be purely notes I consider to be "after-effects/after the experience".

Compared to some other tryptamines, this one seems rather heavy in body load. Pleasantly so, however.

I'd say the total duration for the main substance, including come-up and visual effects residue, was about 4 to 5 hours, with headspace effects being 3 to 4 hours. Cannabis probably only had a minor effect on this.

This was also the least introspective trip on any tryptamine I've had thus far.

An effect I did not note during the experience but distinctly remember: During the peak (so at about T+2:00), I often had moments where anything outside my field of view seemed to be very different if I looked back and forth. At one point, I even tested this. This might be related to the time dilation effect. I'd basically expect some folks to be somewhere in the room, I'd briefly look away, look back, and completely different folks would be right there, in completely different positions.

Another one: At one point, already towards the come-off, the edges of faces/hair of folks and objects around would start to shift in a sort of double vision sort of way, shifting when I move, but would also shift "outwards" when stationary.

After having had some sleep, I still see those added details in many things, including my face, and they are verifiably real, because I can point them out to others and they'll see them too. I just don't seem to have noticed them for a while. I'm sure this perceptual enhancement will fade again sometime soon, but it's interesting to see. I wonder if this is how some folks get really self-conscious about skin blemishes?

At around T+23:50, I walked along a very dark path by a stream of water. There, the particularly dark parts of my environment were oddly highlighted, almost as if they were exuding darkness, similar to how a lamp would work, but for darkness instead of light. Fascinating. Just a bit later, a shadow cast on a house by a tree had a similar effect. Not sure what to make of this, certainly unexpected.

I have to say, I did not notice any such effect earlier, but this is also the first time it has been nighttime since full sobriety set in.

At T+24:01, this effect fades, but I am clearly having a hard time focusing on the dark when surrounded by other light sources. Granted, some of this is normal, but it's even harder than usual.

At T+24:14, I checked my pupil reflexes in a mirror and dimmable light, and indeed, what used to be dinnerplates last night have turned into the opposite. My pupils refuse to widen when given less light.

One day later, at 18:30, I checked my pupil reflexes in the mirror again, and they were back to normal. At precisely 20:00, I've been at the same spot where I noticed the darkness yesterday, it was back to normal, too.

Tryptamines generally fuck with my light perception in a rather short-to-mid-term lasting way, so this might be one of those effects. Another time in the future, I shall avoid doing anything besides 4-PrO-DMT to see if it reoccurs on its own, or if it was caused by my THC intake. Another reason for doing so might be to determine the duration of after-effects.

About ten days later, the detail enhancement in my vision seems to have been of merely perceptual nature; the details are filtered normally when I don't specifically seek them out, but when I do, they're still there. I think this trip just made me more aware of this fact again by preventing this filtering momentarily.
