What is 4-AcO-DMT by Deadhead Chemist?

Deadhead Chemist 4-AcO DMT-also known as O-acetylpsilocin, 4-acetoxy-DMT, psilacetin, or “synthetic mushrooms”—is a semi-synthetic research chemical in the tryptamine family, which also includes the classic psychedelics like DMT and psilocybin. 4-AcO seems to be very closely related to the magic mushroom compounds psilocybin and psilocin, and like psilocybin, is speculated to break down into psilocin in the body during first pass metabolism.

In fact, Deadhead Chemist 4-AcO DMT was first synthesized in the early 1960s by Albert Hofmann, the same chemist who discovered LSD and first synthesized psilocybin. As an employee for the pharmaceutical company Sandoz, Hofmann and his colleague, Franz Troxler, were playing around with molecules similar to psilocin, and patented psilacetin along with four other esters (organic compounds that react to water by producing alcohol) of psilocin in 1963.

But deadhead chemist 4-AcO DMT was patented and then largely forgotten, until it reappeared in the 1990s rave scene as a new designer drug. Then in 1999, professor and psychedelic scientist David E. Nichols tried to put it on the map as a safe and cost-effective alternative to psilocybin, because it’s much easier (and cheaper) to synthesize but more than 20 years later, there still haven’t been any clinical studies on the safety, toxicity, or potential efficacy of O-acetylpsilocin, despite its rising popularity among psychonauts.

Today, psilacetin is comes in the form of a brown or off-white powder (technically a fumarate salt) that can be taken orally or intranasally in micro-doses or more, depending how hard you want to trip—which, depending on how many milligrams one takes, can resemble the effects of mushrooms or DMT, causing many to speculate that 4-AcO has psychedelic properties of its own.

Deadhead Chemist 4-AcO DMT Dosage

Before I start to explain what tripping with deadhead chemist 4-AcO is like, it’s important to emphasize just how dose-dependent the research chemical is. The general consensus among users on message boards and the nine people who filled out a survey I created on 4-AcO, is that lower doses feel like a psilocybin experience, while higher doses start to more so resemble a DMT experience. Or as Sarah*, one of my survey participants, put it, “It was like mushrooms, DMT, and acid in one… like a long DMT trip with the warm and loving feeling of mushrooms, and the mind-blowing experience of acid.”

Deadhead chemist 4-AcO DMT Dose Ranges for Oral Ingestion

  • Microdose: 2.5 – 5 mg
  • Low Dose: 5 – 10 mg
  • Moderate Dose: 10 – 20 mg
  • High Dose: 20 – 40 mg
  • Heroic Dose: 40 mg +

A general reference point indicates that many individuals consider oral doses in the 15 to 20 mg range to closely resemble a 3.5-gram magic mushroom experience. Like all new psychedelics, it’s advisable to commence with a low to moderate dose or even microdose for your initial trip. This approach allows you to familiarize yourself with the terrain before delving into more intense experiences.

For nasal ingestion, doses will differ slightly, as many individuals claim that snorting the powder leads to a stronger but potentially shorter-acting experience. Additionally, a survey participant highlighted the possibility of the powder turning blue in your nostrils. If this occurs, there’s no need for alarm, as it seems to be a common phenomenon.

Deadhead chemist 4-AcO DMT Dose Ranges for Intranasal Ingestion:

  • Microdose: less than 5 mg
  • Low Dose: 5 – 10 mg
  • Moderate Dose: 10 – 20 mg
  • High Dose: 20 – 30 mg
  • Heroic Dose: 30 mg +

For safe dosing, be sure to weigh out your dose on a scale that can read milligrams and if you don’t own one, you should consider investing. They don’t cost more than about $20 and are an easy way to practice harm reduction. Especially with research chemicals that come as powders, a small amount can have a big impact on the strength of the experience.

O-acetylpsilocin Duration

Most folks report an O-acetylpsilocin trip to last more or less the same amount of time as mushrooms but from four to eight hours with an afterglow lasting up to 48 hours after the experience has ended.

Psychonaut Wiki has mapped out the duration as such:

  • Total: 4 – 7 hours
  • Onset: 15 – 40 minutes
  • Come Up: 30 – 75 minutes
  • Peak: 2 to 3.5 hours
  • Offset: 1 – 2 hours
  • After effects: 4 – 48 hours

Deadhead Chemist 4-AcO DMT Trip 

The 4-AcO trip is very dose-dependent. The most common way people describe it is the trip being like a crisp, lucid, and warm mushroom experience on low and moderate doses of about 15 to 30 mg. “Deadhead chemist 4-AcO has a very light and joyous character, almost childlike. Like mushrooms but crisper and clearer,” wrote Steven*, one of my survey respondents, who’s tried 4-AcO at doses ranging from 10 to 50 mg several hundred times. “It’s slightly gentler and more simplified of a trip than mushrooms, but almost the same feeling.”

N,N-Dimethyltryptamine (DMT) is a psychoactive chemical substance found naturally in some plants, animals, and even the human brain, exposing us to this substance. Some cultures utilize DMT for ritual purposes, aiming to alter their consciousness and mood.

Various methods exist for ingesting DMT, with many opting for its crystal form. Smoking it through a pipe or bong, or injecting it, result in powerful yet short trips, believed to be among the most potent hallucinogenic experiences.

Among the numerous “grey market” research chemicals, Buy Deadhead Chemist 4-AcO DMT stands out as one of the safest. This synthetic psychedelic tryptamine shares structural similarities with the molecules found in “magic mushrooms,” namely psilocybin and psilocin.

Many Benefits Come With The Consumption Of The DMT Microdose 4-ACO-Microdosing/4-Acetoxy-N,N-Dimethyltryptamine (Psilacetin Or 4-AcO-DMT) And These Include:

How To Microdose With Deadhead Chemist 4-AcO DMT?

Deadhead Chemist 4-AcO DMT typically sells in a crystallized or powdered form, facilitating various ingestion methods, including oral consumption. However, the preferred and simplest approach is oral intake, despite the substance’s unfavorable taste.

When determining your desired dose, it is crucial to note that altering a few milligrams can significantly impact your experience. According to scientific analysis and reports, the optimal microdose volume falls between 0.5mg and 5mg. If you’re a novice DMT user, it’s advisable to stick to lower volumes, as doses as high as 5mg can be challenging for some individuals.

For beginners, commencing with 1mg allows you to assess your experience for subsequent measurements. Nevertheless, since most scales are not perfectly accurate with such minute amounts, employing the volumetric microdosing method ensures precise dosage confirmation.
