EPT (N-ethyl-N-propyltryptamine) Fumarate Powder

---

N-Ethyl-N-propyltryptamine, commonly referred to as Ethylpropyltryptamine or EPT, is an obscure novel psychedelic substance within the tryptamine class. EPT is chemically related to DMT and is categorized among a series of psychedelic compounds known as unsubstituted tryptamines.

Effects and User Experience

Initial reports regarding the effects of EPT describe them as mild and indistinct when compared to structurally similar base tryptamines such as DMT, DET, and DPT, all of which are known for their powerful psychedelic properties. Among these, EPT is reported to be most similar to DPT, although it is considered less potent and offers a less immersive headspace.

Chemical Structure

As a synthetic indole molecule, EPT features a core structure typical of tryptamines, characterized by a bicyclic indole heterocycle attached at the R3 position to an amino group via an ethyl side chain. EPT is distinguished by the presence of one propyl group and one ethyl group bound to the terminal amine (RN) of its tryptamine backbone. It serves as the N-ethyl analog of DPT and the N-propyl analog of DET, and is also related to compounds such as 4-HO-EPT and 4-AcO-EPT.

Pharmacological Mechanism

Like many psychedelic tryptamines, EPT is thought to act primarily as a partial agonist at the 5-HT2A receptor. The psychedelic effects associated with EPT are believed to arise from its binding efficacy at these receptors. Most serotonergic psychedelic tryptamines exhibit strong structural similarities to serotonin itself, which helps explain their affinity for specific 5-HT sites. It is widely accepted that serotonergic psychedelics, including EPT, produce their effects by acting as strong partial agonists at the 5-HT2A receptors.
