What is 4-ho-dipt

4-HO-DIPT is a psychedelic tryptamine. A homologue of psilocin, this drug likely has similar effects to psychedelic mushrooms. Said to have a rapid onset and relatively short duration for a drug of its class.

4-Hydroxy-N,N-diisopropyltryptamine (also known as 4-HO-DiPT and Iprocin) is a lesser-known psychedelic substance of the tryptamine class. It produces psilocin-like psychedelic effects when administered. It is the 4-hydroxy analog of DiPT and is structurally related to tryptamines like 4-HO-DMT (Psilocin), 4-HO-MiPT (Miprocin), and 4-HO-DET (Ethocin).

Following the publication of its synthesis by David B. Repke in 1977, its effects in humans were investigated by Alexander Shulgin. It is characterized in his 1997 book TiHKAL (“Tryptamines I Have Known and Loved”) and is noted for being unique among psychedelics in terms of its speed (apparent 15 minutes after ingestion), intensity (20 milligrams can produce a transcendent peak experience), brevity (2-3 hours), and dose sensitivity. Additionally, idiosyncratic physical effects.  

Today, 4-HO-DiPT is used for both recreational and entheogenic purposes. It is relatively uncommon and occasionally distributed on the online research chemical market. Very little known pharmacological properties, metabolism, and toxicity in humans, and with limited history of human use. It is highly advised to use harm reduction practices if using this substance.
