4-AcO-DMT is a synthetic psychedelic tryptamine whose effects and duration are very similar to psilocin/psilocybin. Basically when you ingest this substance, the acetylated psilocin turns to psilocybin in your body which produces the effects. This is identical in the way that psilocin in metabolized when psilocybin containing mushrooms are eaten. Most users prefer this over mushrooms though because not only does it save you from having to eat an 1/8th of some dried

mushrooms, but eliminates the sour stomach people often get after ingestion. Another plus of 4-AcO-DMT compared to mushrooms is the dosage needed, with only 15mg to produce full effects. The effects of 4-AcO-DMT are identical to mushrooms. 4-AcO-DMT is a research chemical tryptamine, and has been published with user reports and synth info in the book TiHKAL by Alexander Shulgin.

User Reports 

When scanning trip reports all over the internet I have found an unprecedented amount of extremely positive reports, with the exception of a few who had taken entirely too much and therefore brought them into too intense of an experience.

“I will probably never go back to normal mushrooms again. I can explain the trip as being a really positive and happy trip with a DMT twang to it. DMT is very fun as well so it only adds to the amazing experience. I have been buying 4-AcO-DMT from online retailers for years, but have the hardest time trying to find a reputable dealer who isn’t a low life scammer or going to take a month to get an order out.  I have tried many psychedelics and to this day 4-AcO-DMT is by far my favorite.” -anonymous
