I took 120 mg DiPT oral (after peak 2C-C 10 mg insufflated was added) on a 16 hours empty stomach. Very few trip notes and no quantitative data mean I won't write a trip report, probably (although if anyone has any questions about it, I'll try to answer them here), but one aspect of DiPT's effects (prior to 2C-C insufflation) I'll note here:
During the peak of DiPT's visual effects (c. t+1.30 to t+2.30, I think), I experienced stronger visuals than I can recall experiencing on DiPT before. Still nothing completely astounding, but more than the usual flashing white lights, texture enhancement and slight waviness (all present, especially the flashing which was more extreme than I'd noted on other recent doses); specifically, there were strong visual trails (temporal blurring of visual motion), but they lacked the sharp glowing bloopiness of 2C-x trails; rather they were made of watery mist.
The OEAs were as strong as ever, and took a good few hours to come down from the perceived three-semitone drop and inharmonicity, (Level 3 by t+2.00, Level 2 by t+6.00, Level 1 by t+10.00, baseline by t+14.00; some FM (vocoding) and deepening remained at t+10.00 at least); but CEAs were mostly absent, save for relatively simple modulations in the high-pitched noise, (except during the insufflated 2C-C dose - so maybe I misconstrued the peak of the DiPT - but even then, only to a relatively light degree... no complex harmonized sequences, certainly: this particular aspect of the CEAs I have only glimpsed in recent doses; though I experienced it on a few occasions in the past).
The CEAs seem rather less predictable (less simply dose-dependent) than the OEAs. Odd. I certainly gave the CEAs every opportunity to manifest, I think.
ETA: Actually, on reflection, I probably have enough memories of this to make a vaguely worthwhile brief trip report, so I'll do so some time soon, I expect.
