EPT is a novel research chemical with very limited documentation and extremely sparse user reports. The toxicity profile is unknown and no scientific studies exist on its safety in humans. Effects are described as milder and less immersive than structurally similar tryptamines like DMT and DPT. EPT is typically sold as the fumarate salt rather than the hydrochloride form. Start with very low doses due to individual sensitivity variations and the lack of established safety data.
