Summary PsychonautWiki

2,5-Dimethoxy-4-propylphenethylamine (also known as 2C-P) is a lesser-known novel psychedelic substance of the phenethylamine class. 2C-P is a relatively obscure member of the 2C-x family of psychedelic phenethylamines, which are closely related to the classical psychedelic mescaline. It is known as one of the most potent, dose-sensitive, and long-lasting of the series.

Perspectives

“I was not feeling so good. Hangover, I guess. The material was so gentle in coming on, and soon my body became jangled. Thinking was easy. Verbalizing was easy. Being comfortable with my body was not. My back hurt and then my legs hurt. My lower back was in spasm. At first I did not particularly like what this drug was doing to my body, but took a good look at it and decided that I was the culprit. Took a good look at my drinking so much, and decided that I didn’t need it. So much energy was going through me I didn’t know what to do with it. The whole day was spent in physical discomfort. Food tasted good, and we nibbled all day. My stomach was bloated. Next day I was more or less like a zombie. I was wiped out.”
