Theta:
Glad to hear the ALD-52 was nice and hope this one went well too.

I love smoking 5-MeO-MiPT and we just did ~5 mg to good effect again this morning. I technically can't recommend it enough, but I'm one of those people who is weirdly
really sensitive to getting stronger psychedelics effects from 5-methoxytryptamines too, so I also try not to claim too much about how they'll likely affect others. What I can say though is that for us, it basically eliminates the body load of dosing orally (which we already find light) and while it does compress the heaviest psychedelic effects to around the first hour or so, it still leaves us with an energetic and still trippy high for basically just as long as dosing orally. I honestly don't have much desire to return to using it orally, though it is a bit different and arguably has some distinct uses.
The 5-MeO-MiPT went good too. I rode my bike for like the first hour and a half until my legs started feeling a bit heavy and I started feeling a bit uncoordinated. I think the 5-MeO-MiPT was a bit more visual than the ALD-52, but on the ALD-52 I had more of a tendency to get lost in my thoughts. The 5-MeO-MiPT visuals felt very earthy and there was an oil painting sort of effect. There was a bit more body load with the 5-MeO-MiPT and it felt a bit frantic and discombobulated at a couple points, but that might have also been the fact that I had twice as much espresso the morning of.
Whereas I actually thought about a couple fairly dark things on the ALD-52, the experience itself never felt dark. The 5-MeO-MiPT seemed a bit more intrinsically strange and a little dark, even though I never explicitly dwelled on any negative ideas. Being among people on the 5-MeO-MiPT also felt somewhat uncomfortable, which was totally the opposite of how the ALD-52 felt. Overall the ALD-52 felt like a much richer experience and seemed to have more transformative potential.
The 5-MeO-MiPT body high was a quite sharp and distinctive feeling in my extremities. The ALD-52 body feeling was less overt and was more of a supreme relaxation, which I actually preferred. Taking a hot shower on the ALD-52 felt amazing as well. I actually read something you posted about 5-MeO-MiPT's duration being 10-11 hours and that ended up being right on the money for me. Although it was fairly subtle after the first five or so hours, it took about 11 hours before I was sure the experience was over. That's pretty cool that the overall 5-MeO-MiPT duration doesn't change much when vaped, I definitely want to try that soon.
One thing that kind of held me back from using psychedelics the past few years was that in my sober state I had accumulated all these irrational thoughts that I projected onto the psychedelic experience. I think it was mainly my abuse of dissociatives, which I think truly are drugs that induce psychotic patterns of thought, that led to this. However once I'm actually in the psychedelic experience I realize how crazy these thoughts are and I feel even more confident in my survival instincts than when sober. Any sort of obsessive-compulsive thought patterns I can also see right through and realize how silly they are. On the ALD-52 I thought about my use of dissociatives and I realized that I do regret abusing them to the extent that I did, but it was mostly a peaceful acceptance rather a self-flagellatory sort of realization. I'm just so glad that I've quit dissociatives for good because now the healing process will be continuous rather than intermittent.
Probably the best thing I noticed with the 5-MeO-MiPT but especially with the ALD-52 was how the smooth the descent was, absolutely no trace of headache which was a huge plus for me. I got absolutely brutal headaches on the comedown the past few times I used 2C-B and the one time I used 2C-B-FLY, along with more minor headaches from 2C-C and 2C-D. I used to love 2C-B and I've used it more than any other psychedelic but I probably won't use it again for this reason. 2C-C is even better than 2C-B I think, so I really hope it was just a one-time thing with 2C-C, but unfortunately there does seem to be a pattern with the phenethylamines giving me headaches on the comedown (6-APB, MDA & MDMA give me similar types of headaches on the comedown FWIW and that's one big reason I haven't rolled in a few years, although I would love to try AMT as it sounds absolutely beautiful).
Some people suspect the headaches are caused by rebound vasodilation but I've found vasoconstrictors like caffeine offer very little relief for these headaches. I think a better hypothesis is that prostaglandin E2, which is known to induce migraines, accumulates as a result of 5-HT2AR-mediated arachidonic acid activation. Acetaminophen stops these headaches in their tracks for me, and sure enough it's been show to inhibit prostaglandin E2 synthesis. Anyways, I wouldn't be surprised if some of the phenethylamines are more prone to inducing headache due to increased functional selectivity for the arachidonic acid pathway relative to tryptamines and lysergamides.
Edit: Thought I'd add that the day I took ALD-52 it was quite sunny while the next day it was quite blustery with dark skies, which may have influenced my perception of the 5-MeO-MiPT. Also have a great afterglow today with an uplifted mood and enhanced color saturation. I was able to make an 8 hour drive which I needed 4F-MPH to make last time and never really got frustrated despite being in the car for so long. I even felt like my focus was better and like I was less "on autopilot" than when I made the drive on 4F-MPH.
