Update at T+11:00. I'm still at +1 with visual enhancements, body high, etc.. The trip peaked at a solid +2 with some good CEVs and good color and visual detail enhancement with eyes open. From what I experienced, I believe this will be a highly visual substance at 6mg+.
This 4mg went a long way. I was apprehensive going into this. For one thing, I expected 4 mg would bring a lot more body effects than 2 mg. For another, I worried that the ++ level at 4 mg would be awkward and uncomfortable for the many hours this substance lasts.
Right after I posted above at T+1:15, I felt the first significant wave, which was very euphoric. And then it just kept building in waves of "heart energy" and euphoria through T+5:00, after which it began a very gradual decline. Body load was minimal for me at this dose, which bodes very well for taking it higher. At the same time, the intensity of the experience was really off-the-charts when considering the tactile and emotional euphoria. It was luscious and exhilarating. Admittedly I'm a bit intimidated by going to 6 mg just because of that intensity, and I certainly wouldn't want to get on the "bad side" of this substance. That said, I've pretty much always been able to stay on the "good side" of 2C-E, so I may just be unusually compatible with these substances.
My partner joined me later, matching my peak with 15 mg of 2C-D. She's such a lightweight these days, I was surprised that we under-dosed her a bit, but she said she got along very well with the 2C-D and will try more next time.
All and all, this was an incredible day with an incredible substance. It may indeed displace 2C-E and mescaline (tied) as my favorite psychedelic substances. Though, it does come with the cost of having to devote an entire day (and then some) to the experience. I also wonder if has a bit less depth than 2C-E (and mescaline) in terms of guidance and insight. While I engaged in plenty of introspection today, nothing really pulled me in, and I mostly felt hedonistic. I will need to be well prepared for my 6 mg trial, and I doubt I will ever take this stuff higher than 8 mg. Even that seems like it would be insane.
