What Is 4-AcO-DMT? Effects, Dosage & Safety Guide (2025)
Nov
4-AcO-DMT, sometimes referred to as psilacetin or O-Acetylpsilocin, is a laboratory-created compound that mimics the psychoactive effects of psilocybin mushrooms. Users frequently explore this substance for emotional clarity, creativity enhancement, introspection, and controlled psychedelic experiences. This complete guide explains everything you need to know about its effects, history, chemistry, microdosing, safety, protocols, and user experiences in 2025.
What Is 4-AcO-DMT?
This DMT is best described as a synthetic psilocybin analogue that converts into psilocin when ingested. This conversion activates serotonin receptors, influencing mood, sensory perception, and cognitive processing. Many users consider it smoother and more predictable than organic mushrooms.
Also referred to as:
• Psilacetin
• O-Acetylpsilocin
• A psilocin analogue
• A tryptamine compound
Available forms: powder, capsules, and liquid solutions.
Some individuals search specifically for 4 ACO DMT effects because the experience tends to feel calmer and cleaner than traditional mushroom trips.

History and Chemistry
4-AcO-DMT was originally synthesized in the 1960s to explore consciousness and study the biochemical nature of psychedelic experiences. Today, it is still considered a research chemical, examined for how psilocin analogues interact with the mind.
Its O-Acetyl group differentiates it from psilocin, allowing smoother absorption and a lighter physical load. Because of this, many microdosers and introspective users prefer it over traditional psilocybin.
