Summary
N,N-Dipropyltryptamine (also known as Dipropyltryptamine, DPT, and "The Light") is a lesser-known psychedelic substance of the tryptamine class. It is closely related to DMT and is reported to be uniquely similar in its hallucinogenic intensity, albeit with a moderately longer duration and greater unpredictability relative to DMT and other psychedelic tryptamines.
Perspectives
“DPT is a very intense psychedelic that hits hard and fast. Not for the faint of heart, but absolutely worth it for those willing to put up with the intensity and deep discomfort.”
“This started sooner and was a lot stronger than I had expected. I had trouble talking and I felt very uncomfortable. I think physically I was in a chair but I was on a kind of mountain surrounded by clouds. And the clouds talked to me.”
