O-Acetylpsilocin
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.
Dosage
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. While extremely strong doses of 4-aco-dmt seem to be well tolerated physically, it is ill-advised to jump into extremely large doses.
