Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.

Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.

This is an Experimental Substance with little data. This is most likely because the substance is is not very old. Information is limite and incomplete.

Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

A quite potent tryptamine that has be related to having “shroom-like” visuals. Yet without much bodyload. Very hydroscopic. Seems to be quite safe in dosing. Similar to the likes of 2C-B.

Summary

It is the acetylated form of 4-HO-MiPT (also known as miprocin) and is a higher homolog of 4-AcO-DMT, 4-AcO-MET and 4-AcO-DET. These substances are commonly hypothesized to act primarily as prodrugs for their respective hydroxylated counterparts (e. g.

4-HO-DMT, 4-HO-MET and 4-HO-DET), although there is on-going debate as to whether they possess their own innate activity. There is very little information on the human pharmacology or toxicity of 4-AcO-MiPT, although analytical methods have been developed for its detection. Today it is either used recreationally or as an entheogenic substance and is typically acquired through the use of online research chemical vendors.

It remains relatively uncommon and has very little history of human usage.

Chemistry

Tryptamines share a core structure comprised of a bicylic indole heterocycle attached at R3 to an amino group via an ethyl side chain.

4-AcO-MiPT is substituted at R4 of its indole heterocycle with an acetoxy (AcO) functional group CH3COO−.

It also contains isopropyl and methyl chains bound to the terminal amine RN of its tryptamine backbone (MiPT). 4-AcO-MiPT is the N-substituted methisopropyl homologue of 4-HO-DMT (psilocin).

4-AcO-MiPT is the acetate ester analog of MiPT and the N-substituted methisopropyl analog of 4-AcO-DMT.

Legal Status

Due to its relative obscurity, the possession and sale of 4-AcO-MiPT is unscheduled in most countries.

  • Germany: 4-AcO-MiPT is controlled under the NpSG (New Psychoactive Substances Act) as of July 18, 2019. Production and import with the aim to place it on the market, administration to another person and trading is punishable. Possession is illegal but not penalized.

  • Sweden: 4-AcO-MiPT is classified as "health hazard" under the act "Lagen om förbud mot vissa hälsofarliga varor" (translated to the "Act on the Prohibition of Certain Goods Dangerous to Health"). The drug is listed in their regulation SFS 2005:733, making it illegal to sell or possess.
  • United Kingdom: 4-AcO-MiPT is a Class A drug in the UK as it is an ester of the drug 4-HO-MiPT., which is a Class A drug as a result of the tryptamine catch-all clause.
  • United States: 4-AcO-MiPT is unscheduled in the United States. It may be considered an analogue of psilocin (4-HO-DMT) which is a Schedule I drug under the Controlled Substances Act. As such, the sale for human consumption or the use for illicit non-medical or industrial intents and purposes could be prosecuted as crimes under the Federal Analogue Act.
