DPT
Aliases: N, N-dpt, The light, Dipropyltryptamine
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.”

Tolerance
Tolerance Decay
General serotonergic psychedelic pattern inferred from community and classic literature: substantial tolerance for several days with return towards baseline over 1–2 weeks. DMT shows atypical rapid tolerance dynamics; DPT likely follows the more typical pattern due to its longer duration. Data quality: mixed (anecdotal + extrapolation).
