Buy 4-AcO-DET Fumarate is a high-purity research chemical (available in powder or pellet form). Laboratories and researchers use it to study tryptamine pharmacology, prodrug metabolism, 5-HT₂A receptor activation, and psychedelic structure-activity relationships.
What is 4-AcO-DET?
4-AcO-DET (4-Acetoxy-N,N-diethyltryptamine), also known as Ethacetin, is a synthetic psychedelic tryptamine. It serves as the O-acetylated prodrug of 4-HO-DET. After ingestion, it is rapidly metabolized into the active compound 4-HO-DET. First synthesized by Alexander Shulgin, it is known for producing rich visual effects with a relatively clear headspace. Sold strictly for laboratory and research purposes only.

Effects (Research Observations)
4-AcO-DET is metabolized to 4-HO-DET and acts primarily as a 5-HT₂A receptor agonist. Reported research observations include:
- Strong visual effects (geometric patterns, color enhancement, fractals, tracers)
- Euphoria, mood elevation, and enhanced sensory perception
- Altered thought patterns, introspection, and time distortion
- Onset: 20–60 minutes (oral)
- Duration: 4–7 hours
Important Note: These are not approved medical effects. Risks include nausea, anxiety, psychological distress, increased heart rate, and challenging experiences at higher doses. Strictly for research use only — not for human consumption.
