4-HO-DiPT crystals – More information
4-Hydroxy-diisopropyltryptamine (also known as 4-HO-DiPT and Iprocin) is a lesser-known psychedelic substance of the tryptamine class that 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 like muscle tremors and bodily malaise were noted.
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 is known about the pharmacological properties, metabolism, and toxicity in humans, and it has a limited history of human use. It is highly advised to use harm reduction practices if using this substance.

4-HO-DiPT, or 4-Hydroxy-N,N-diisopropyltryptamine, is a synthetic indole alkaloid molecule of the tryptamine chemical class. Tryptamines share a core structure comprised of a bicyclic indole heterocycle attached at R3 to an amino group via an ethyl side chain. 4-HO-DiPT is substituted at R4 of its indole heterocycle with a hydroxyl functional group OH−. It also contains two isopropyl groups bound to the terminal amine RN of its tryptamine backbone.
The toxicity and long-term health effects of recreational 4-HO-DiPT use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 4-HO-DiPT is a research chemical with very little history of human usage.
Anecdotal reports from those who have tried 4-HO-DiPT suggests that there are no negative health effects attributed to simply trying it by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.
It is strongly recommended that one use harm reduction practices when using this drug.
4-HO-DiPT is not habit-forming and the desire to use it can actually decrease with regular consumption. Like with most psychedelics, it is most often thought to be self-regulating.
Tolerance to the effects of 4-HO-DiPT are built almost immediately after ingestion. After that, it takes about 3 days for the tolerance to be reduced to half and 7 days to be back at baseline (in the absence of further consumption). 4-HO-DiPT presents cross-tolerance with all psychedelics, meaning that after the consumption of 4-HO-DiPT all psychedelics will have a reduced effect.
Due to its relative obscurity, the possession and sale of 4-HO-DiPT is unscheduled in most countries.
