O-Acetylpsilocin (also known as Psilacetin, 4-Acetoxy-DMT, or 4-AcO-DMT) is a synthetically produced psychoactive drug with a limited history of use. Its effects and duration are similar to those of psilocybin/psilocin although it is sometimes described as "warmer" or "more euphoric" than psilocybin-containing mushrooms. It is probably metabolically converted into psilocin in the body, but there are also reasons to believe that 4-acetoxy-DMT might itself be active in the brain, producing effects that are distinct from psilocin.
Ideal dosage varies widely between individuals. Some people get very heavy mental effects and others find the mental effects light. It's best to start low and see how you are impacted.
Heavy: 40mg+ (while extremely strong doses of 4-aco-dmt seem to be well tolerated, it is ill-advised to jump into extremely large doses)
Onset: 20-45 minutes (empty stomach) up to 120 minutes depending on stomach contents
Peak: 3~4 hours
Total Duration: 6~8 hours
After-effects: 2~4 hours
