2c-e and 2c-p were both extremely visual, probably the most visual psychedelics I have tried, with the possible exception of DPT. They are about equal in terms of visuals and intensity, the main difference is that 2c-p is almost twice as potent as 2c-e and the effects last 40-50% longer. 2c-p also seemed to be more euphoric.
16mg of 2c-p was as intense as 25-30mg of 2c-e. I hope I can come across some 2c-p again sometime.
2c-b was also very visual, and more euphoric than 2c-e. 2c-c is just as visual at high doses.
I prefer 2c-e and 2c-p, but 2c-b would probably be the best choice for someone who is just looking for a good time.
DOC and DOI can be as visual as 2c-e, but they seemed to have more variation in visual intensity. They can both be very euphoric as well.
As for tryptamines, DPT is the most visual one I have tried. 75mg DPT by IM injection seemed every bit as visual as any 2c-e or 2c-p experience. I would have felt comfortable going higher with DPT, I could imagine it surpassing anything I've tried at a higher dose. IV DPT was even more visual. I don't remember the exact dose, I am thinking it was 36mg. Visuals were almost blinding and I experienced a lot of ego loss with that. I thought I was going to die for a couple of minutes after injecting.
4-ho-mipt was also highly visual. Maybe not quite as much as the others I have listed, but the visuals were more bizarre. It also caused a lot of sound distortion and hallucinations. It was probably the most euphoric psychedelic I have tried.
5-meo-amt was less visual than most and not very interesting either. The visuals were quite different in character from any other psychedelic I have tried. It was not very intense unless I used a high dose. The side effects can be very bad for some people, but I did not find them too bad unless the dose was high.
If looking for something that is not too intense mentally, I'd go with 2c-b or 2c-i. 2c-b is the more visual of the two, but I'd also say it is more intense. 2c-c may also be a good choice. While it seemed quite deep, it was also gentle. It did not seem likely to get out of control.
5-meo-mipt was not very visual, but it felt really nice and is not very intense unless a high dose is taken. It can be quite visual at higher doses, but it was just as intense as a 4-5g mushroom trip at those levels.
