What is 4-HO-EPT

The tryptamine class associate is 4-HO-EPT. 4-HO-EPT or 4-Hydroxy-N-ethyl-N-propyltryptamine is a chemical that is said to induce psychedelic effects. According to anecdotal evidence, cognitive effects include mood changes and altered behaviour. It is structurally very similar to psilocin (4–HO-DMT), a compound from the same class. The active component of magic mushrooms and psychedelic mushrooms is 4-HO-DMT. It acts on the brain’s receptors. Important to remember that 4-HO-EPT can’t be consumed by humans. However, it is important to take sufficient precautions when conducting experimental research.

4-HO-EPT is a synthetic psychedelic compound that is sometimes used in research for its effects on serotonin receptors in the brain. It is a relatively new research chemical and there is limited scientific research available on its pharmacology and potential effects.

As with all research chemicals, it is important to handle 4-HO-EPT with care and caution. Researchers should be well-informed about the proper safety precautions, dosing guidelines, and potential risks associated with its use. It is also important to ensure that research is conducted in accordance with local regulations and ethical guidelines.

It is not recommended to use 4-HO-EPT for any purposes other than research, as its effects on the brain and body are not fully understood and could be potentially dangerous. If you have any questions or concerns about the use of 4-HO-EPT in research, it is best to consult with a qualified professional or a reputable research institution.


The tryptamine class includes 4-HO-EPT. All tryptamines, including 4-HO-DMT (the key ingredient in magic mushrooms), share a structure that includes an amino group mounted on a bicyclic heterocyclic indole heterocyclic. This is attached at R3 by an ethyl sidechain.

At R4 of the indole heterocycle, a hydroxyl functional band OH- causes a substitution. A propyl and an ethyl chain are bound to the tryptamine backbone. They link to the terminal amino Rn.

4-HO-EPT Effects

Similar to most psychedelic attemptptamines, 4-HOEPT acts principally as a HTML2A partial agonist. The 4-HO-EPT binding ability at 5-HT2A receptors is believed to be the key to the psychedelic effects. The role of these interactions in the psychedelic experience is still unknown.
