A Thorough Assay of DPT

Due to the plain lack of data on this chemical, the entry on DPT in the TIHKAL was invaluable. I used Shulgin’s recommendations for assaying new materials, as it is consistent and recognizable. I have also used the “Shulgin rating scale” from PIHKAL.

There was obtained 1g N,N-dipropyltryptamine hydrochloride for the purpose of bio-assessment.

For context, I am a trans woman in her early 20s, currently in school to enter research pharmacology. I have used more than 20 unique psychedelics and tripped about 100 times. Needless to say, I am an experienced traveler.

For a general allergy and taste taste, 5mg was placed on and under tongue. Taste very bitter and irritating, almost unbearably so. No effects. -

(with 50mg, orally) No effects -

(with 100mg, orally) A suggestion of some activity at about 30 minutes, that did not develop further. While not inactive, there seems nothing of value at this level. Baseline at less than 90 minutes. +

(with 200mg, orally) A clear alert at 10 minutes, and I became aware of an inaudible but deeply felt hum. The “sound” was grounding and familiar. At 20 minutes the closed eye visuals were geometric and inorganic. Sharp night-vision green kaleidoscopic fractal patterning, like a hologram. At the one hour, the deep humming became more defined, a vibrato pulsing that encouraged me to lie down. Shadows suggesting human shapes flickered on the wall in impossible colors, projected by an absent fire. The wall beside me became sand-like in color and texture. Geometric visuals seemed to all but disappear, for my attention was suddenly captured by a hallucination of what I can best describe as an ancient Egyptian relief — a person wearing a headdress — a wolf or dog. Symbols were revealed, an Ankh clearly visible, among other symbols. Some appeared to be hieroglyphics, others unlike any I’d seen. I looked to the eyes of the person-in-the-wall, felt the words “not yet” communicated to me, before the hallucination wore away. At 90 minutes there was a sharp drop, and there were only light/residual effects until baseline was reached at approximately 3 hours.

I cannot call this a “pleasant” experience, but oh my was it interesting. I would choose to explore the oral route at a higher dose, but I do not have enough of the material to do so. +++

(with 20mg, insufflated) Painful after a few seconds of contact with mucous membranes. Moderate burning sensation in back of throat and sinus as it drips. Feel first alert after about two minutes. A subtle shifting of consciousness developed over 20 minutes, an indescribable “on” that accompanies most psychedelics. There is a thickness to the air, but otherwise no visual activity. After about 30 minutes the effects drop off quickly. Baseline at one hour. +

(with 40mg, insufflated) first alert was at less than a minute. At five minutes, mild visual distortions, things seem to be moving. For about 45 minutes I lay in bed listening to Aphex Twin as rapid geometry patterned with euphoric synergism to the music. At about 1 hour the effects dropped off rapidly, baseline by 90 minutes.This is a pleasant level, but not very interesting. ++

(with 80mg, insufflated) Felt the first alert only seconds after insufflation. Some of the material got caught in my sinus, which was painful and nauseating. I hurried to the bathroom in time to vomit before I started tripping. Flickering blues and greens sparkled in my vision, holographic triangles dripping out of form. At about 10 minutes, I had closed my eyes for just a moment, and upon opening them the entire room appeared to have rotated 180°, every surface became purple and white pinstripes, flowing like white water rapids. I was disoriented and scared, this was an utterly alien sensation. There was an undeniable presence in the room, and it did not feel friendly. I realized I was able to perceive the room unaltered simultaneously, and doing so brought me out of the hallucination. At 30 minutes the intensity of the experience dropped off rapidly, but some visual distortions lingered until about the two hour mark. Baseline at 2 hours 15 minutes. +++

(with 120mg, insufflated) 120mg of DPT is a lot of powder, and it was an effort in itself just to ingest it by this route of administration, especially because it is so irritating to mucous membranes. Onset in less than a minute. A deep pulsing hum washed over me as I coughed from the irritation of the chemical dripping down my throat. The visuals were choppy and sharp, chaotic, glitching green transparent shapes that obstructed my vision. At 5 minutes the hum grew into a deafening buzzing that filled me with a profound sense of euphoria. At 10 minutes I felt pushed into the ground by it, the hum overtook me and absorbed me into its warmth. The hum became my entire perception. I could not separate my body from the sound, but I did remain aware of having a self — this was not an ego death. When I was able to locate myself in corporeality, a check of the clock revealed it had only 40 minutes had passed since administration. It continued to drop quickly — at an hour the effects were only residual, very minor visuals fading off to baseline at two hours. This level seemed to produce a lot of darting (involuntary muscle contraction). I will not run up the dose on this ROA further. +++

(with 30mg, i.m.) There was dissolved 30mg DPT in .5mL purified water, injected into the vastus lateralis (thigh). First alert at five minutes, followed by a definite sense of coming up, which never developed beyond a subtle shifting of consciousness, which dropped as quickly as it began. This is perhaps simply too low a dose. Though administration was careful, pain at the injection site persisted for two days. I will refrain from exploring this route of administration further for now. +

(with 10mg, i.v.) There was dissolved 10mg DPT in .2mL sterile saline solution, injected into the cephalic vein (crook of arm). Onset was instantaneous — a massive rush of euphoria, the air became thick and dripped with ever-shifting geometry. I was immobilized but pleasantly so. I felt a push to close my eyes, simply enjoying the beautiful, impossible shapes dancing and transforming behind my eyelids. Sharp drop in activity at about 8 minutes, and I was able to speak with my trip-sitter. Baseline at 20 minutes. This was a wonderful serene experience. +++

(with 20mg, i.v.) There was dissolved 20mg DPT in .5mL sterile saline solution, injected as previously described. At 1 second, my whole visual field was disintegrating, as that familiar buzz-hum roared through my entire being. At 2 seconds, I felt a pressure around me — like I was in a centrifuge. At 3 seconds, this pressure became an unstoppable force, and I couldn’t tell if my eyes were open or closed. Impossible kaleidoscopic motion rapidly decayed, swirling apart like galaxies bursting and losing all form, a chaos like every individual star moving in a different direction. I realized I was dying, but I was not afraid. Some part of me knew it was not a literal death of the body, so I thought “I accept this death”, and I died.
Infinite luminous light. Nothing. All. I could not describe this eternal moment.
Ineffable, everything.

I opened my eyes, the visual noise gathering itself back into cosmic order. Once I was able to identify that I was back, the supreme intensity of the experience dropped as abruptly as it had begun. It felt like it had all happened in one second, but was in fact 15 minutes. I was speechless for several hours, completely rapt in awe and reverence. ++++
