Aliases: Diisopropyltryptamine
Summary
N,N-Diisopropyltryptamine (also known as Diisopropyltryptamine and DiPT) is a lesser-known psychedelic substance of the tryptamine class. It is a structural analog of DMT and related to various psychedelic tryptamines such as 4-HO-DiPT, 5-MeO-DiPT, and MiPT. The first human trials of DiPT were undertaken in 1975 by Alexander Shulgin, who would co-author and publish a paper detailing its synthesis and human psychopharmacology in 1981.
Perspectives
“This drug did exactly as advertised. It's a curious experience but so far hasn't proven to be much beyond that.”
“Wild effects noted in an hour. Remarkable changes in sounds heard. My wife’s voice is basso, as if she had a cold—my ears with slight pressure as if my tubes were clogged but they aren’t. Radio voices are all low, music out of key. Piano sounds like a bar-room disaster. The telephone ringing sounds partly underwater. In a couple more hours, music pretty much normal again.”
