My favorite one is 2c-p. It had the same depth to is as 2c-e, but was more potent, longer lasting, and seemed a little more intense than 2c-e. The nausea was maybe a little worse than with 2c-e, but otherwise the side effects were about the same. It is very similar to 2c-e. The most significant difference is the level of euphoria it often induced. 2c-e could be very euphoric at times, but 2c-p was more consistently euphoric. Both chems also caused feelings of depression and despair regularly, usually involving the knowledge that there were things that I needed to change in my life or the intense recall of negative memories(almost like reliving them).
2c-p was the most intense of the 2c's, mentally and visually. All of the trips were very interesting and at times I was almost out of body. On one occasion, I became unaware of my body for a while. On one trip, I thought I was having spiritual/religious conversion but I returned to being agnostic just as I have after other spiritual experiences.
It has been a long time since i've had any, and I got some 2c-e not long ago. The second batch of 2c-e was much less interesting than the first, not sure if that is because it was different or it just doesn't work well for me any more. I hope if I ever get any more 2c-p that it will be as good as the first.
