Finally got round to trying this one after holding onto 10 x 50mg pellets for several years. Based on other reports I have no reason to believe they lost any potency, especially as they were stored away from light, heat and moisture.
All trials taken orally on an empty stomach, with no cross tolerance (all taken at least 1 month after previous psychedelic experience).
Regardless of dose, I found the duration to be approximately:
Onset - t0:00 - t0:45
Coming Up - t0:45 - t1:00 (very quick)
Plateau - t1:00 - t2:30
Coming Down - t2:30 - t3:30
After Effects - t3:30 - t5:00
Back to baseline by t6:00, albeit with a headache (this was stronger with higher doses).
First trial - 100mg
At this dose I found it similar to ~1g of shrooms - enough to get moderately strong negative physical effects with only mild psychedelic effects. Unfortunately I spent most of the plateau on the toilet with terrible diarrhoea, watching faint kaleidoscopic effects in the bathroom tiles. This eventually wore off, leaving me to lie down and enjoy some emotional introspection along with music enhancement.
I was still feeling a fairly strong stomach ache but around t4:00 felt sober enough to go for a walk with a joint which helped me feel a bit better. Residual stimulation wore off around the 6 hour mark, with no effect on sleep.
Second trial - 150mg
This time I preloaded with 4mg loperamide to prevent diarrhoea, which worked really well. There was still quite a bit of stomach discomfort, but I was able to appreciate the trip much better without being stuck on the toilet for most of it. Psychologically it was similarly manageable to the previous trial, though the music enhancement was much greater and I ended up spending the plateau watching live music performances and reflecting on my current life circumstances. I noticed a quite strong restless leg which I didn’t have the first time. I get this quite often with psychedelics, especially more stimulating ones like LSD, so I wasn’t particularly concerned.
Around t5:00 the discomfort had mostly subsided and I started to feel some erotic effects which I greatly enjoyed (I experience this with most tryptamines towards the come down). Again, at about t6:00 I felt back to baseline with a headache, slightly stronger this time and leading into the morning. Despite getting a good 8 hours sleep I still felt somewhat slow and hungover the following morning, though this wore off by the afternoon.
Third trial - 250mg
In addition to 4mg loperamide, I also preloaded with 8mg ondansetron to mitigate as many of the negative physical effects as possible. This did help, and despite the higher dose the stomach discomfort was reduced but still quite noticeable. As usual I started coming up around the t0:45 mark, and put on some music. I notice the restless leg much stronger this time, and by t1:00 I was feeling seriously high and needed to lie down. I could hear a familiar tryptamine ‘buzz’ which soon turned into a very pleasurable full-body vibration. I shut my eyes and felt myself leaving my body and just focusing on the increasing sensation which was becoming more and more euphoric.
At this point I am vaguely aware of my legs shaking and rubbing together which seemed to increase the pleasure to an incredible degree. Soon it felt like the most psychologically erotic experience of my life as I felt the pleasure drowning out any other stimuli, both my surroundings and any sense of self awareness. At this point I had no idea of my sex, gender, sexuality, or even humanity - all I felt was that I was being absolutely dominated by some pure primeval force and, despite not usually being particularly submissive, I was absolutely loving it. I felt like I must have transformed myself into some sort of cosmic slut (!) and was happy to leave any previous existence behind in awe of this new found power coursing through me. This went on for about 90 minutes before it started to subside and I started to remember who I was along with my surroundings.
I stay lying down in a confused but happy afterglow - how was it possible to have such intense tryptamine eroticism in such a detached, out-of-body way? I wasn’t even aware of being human, let alone a male capable of erection, yet every other sexual experience I’ve had on psychedelics has had a very strong bodily component. The closest experience I’ve had was with high doses of snorted DMT which had a similar feeling of being forced to submit to a god-like power but without any of the eroticism, and was far less immediately euphoric.
Around t4:00 I am already starting to return to normal, though with a stronger headache which again persisted into the following morning. Funnily enough I was actually far too worn out to actually masturbate, and went to sleep fairly easily at around t7:00. However, every orgasm I have had since has been greatly enhanced and comes alongside a strong memory of the intense euphoria, even two weeks later.
Summary
Overall some incredible effects which I have never experienced before with any other high dose psychedelic, or indeed any other drug. However I must emphasise that the unpleasant physical side effects are very strong, especially the diarrhoea, and that there may be better alternatives - I have never tried 5-MeO-DiPT which is closely related and is also known for both eroticism and stomach discomfort, but is much more popular. 5-MeO-MiPT also sounds like it has some similarities, I hope to be able to try both of these one day.
I should also encourage anybody considering trying 5-MeO-DiBF to titrate their doses more gradually, I only made the leap from 150mg to 250mg because I only had 250mg remaining and am unable to acquire any more. The previous highest reported dose I found was 200mg, and there are not many trip reports available on this one at all.
