4-HO-EPT crystals – More information
4-Hydroxy-N-ethyl-N-propyltryptamine (also known as 4-HO-EPT or Eprocin) is a novel synthetic psychedelic substance of the tryptamine chemical class that produces psychedelic effects when administered. It is structurally related to psilocin (4-HO-DMT), the active component in psilocybin mushrooms, and produces similar effects.
Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-HO-EPT. It has no history of human use before being sold online as a research chemical in 2016. It remains obscure and is either used recreationally or for research purposes.

4-HO-EPT, or 4-hydroxy-N,N-diethyltryptamine, is a synthetic indole molecule of the tryptamine 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-EPT is substituted at R4 of its indole heterocycle with a hydroxyl functional group OH−. It also contains a propyl and ethyl chain bound to the terminal amine RN of its tryptamine backbone (EPT).
The toxicity and long-term health effects of recreational 4-HO-EPT use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 4-HO-EPT is a research chemical with very little history of human usage.
Anecdotal evidence from people within the community who have tried 4-HO-EPT suggests that there are no negative health effects attributed to simply trying the 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 substance.
4-HO-EPT 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-EPT 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-EPT presents cross-tolerance with all psychedelics, meaning that after the consumption of 4-HO-EPT all psychedelics will have a reduced effect.
Due to its relative obscurity, the possession and sale of 4-HO-EPT is unscheduled in most countries.
