Ethylpropyltryptamine (EPT Fumarate)

N-Ethyl-N-propyltryptamine also known as Ethylpropyltryptamine (EPT Fumarate) is a new obscure psychedelic drug from the tryptamine class. EPT is chemically similar to DMT and belongs to a group of psychedelic compounds known as unsubstituted tryptamines.

The date of origin of the original synthesis of the Ethylpropyltryptamine (EPT Fumarate) is so far unknown. This product first appeared for sale in the online chemicals market in 2016. Unlike most chemicals, Ethylpropyltryptamine (EPT Fumarate) has no documentation or instructions for use in the literature. scientist. This product appears to be an entirely new clandestine drug design product.

Basic reports describe the effects of Ethylpropyltryptamine as mild and indistinct compared to structurally similar basic tryptamines such as DMT, DET, and DPT, all of which are very potent psychedelics. Of these, it would be the most similar to the DPT, albeit less powerful and with less immersive headspace.

Almost no information exists on the pharmacological properties, metabolism and toxicity of EPT Fumarate. It is strongly recommended that you use harm reduction practices while using this substance.

Chemistry of Ethylpropyltryptamine (EPT Fumarate)

EPT Fumarate, or N-ethyl-N-propyltryptamine, is a synthetic indole molecule of the tryptamine chemical class. Tryptamines share a main structure consisting of a bicyclic indole heterocycle attached at R3 to an amino group via an ethyl side chain. EPT Fumarate contains a propyl group and an ethyl group linked to the RN terminal amine of its tryptamine backbone.

EPT Fumarate is the N-ethyl analog of DPT and the N-propyl analog of DET. It is also an analogue of 4-HO-EPT and 4-AcO-EPT.

Ethylpropyltryptamine (EPT Fumarate)


As with most psychedelic tryptamines, EPT Fumarate is believed to primarily act as a partial 5-HT2A agonist. The psychedelic reactions are believed to stem from the efficiency of EPT Fumarate binding to 5-HT2A receptors.

However, the role of these interactions and how they result in the psychedelic experience remains the subject of ongoing scientific research.
