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.

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.

N,N-Dipropyltryptamine, a psychedelic tryptamine compound and lesser-known analogue of DMT, with similar psychedelic effects. Like DMT it is a partial serotonin receptor agonist.


It is closely related to DMT and is reported to be uniquely similar in its hallucinogenic intensity, albeit with a moderately longer duration and greater unpredictability relative to DMT and other psychedelic tryptamines. DPT was first synthesized in 1950. Human use was first reported in 1973, where it was researched in low doses as an adjunct to therapy for alcoholism.

It has also been researched in high doses to induce peak experiences for terminal cancer patients. It has gained some notoriety for its adoption as the primary sacrament for the “Temple of the True Inner Light” in the United States, a Christian off-shoot organization who believe in the ritual use of psychedelics and refer to them as “the true flesh of God. " DPT is commonly consumed via insufflation or orally.

Many report the experience of insufflation to be very congestive and painful which, with the rapidness of onset, does not give the user much time to acclimate themselves to its powerful effects. It can also be administered intramuscularly or via vaporization after conversion to the freebase form. Smoking the freebase is reported to be the preferred route used by the “Temple of True Inner Light”.

Very little data exists about the pharmacological properties, metabolism, and toxicity of DPT, and it has relatively little history of human usage. It has long been available on the research chemicals market as a legal, grey-market alternative to DMT, and commercially distributed through online vendors. Many reports also suggest that this substance may be overly difficult to use safely for those who are not already very experienced with hallucinogens.

It is highly advised to approach this powerful psychedelic substance with the proper amount of precaution and harm reduction practices when using it.


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

DPT contains two propyl groups carbon chains bound to the terminal amine RN of its tryptamine backbone. DPT has a number of substituted analogs such as 4-HO-DPT or 4-AcO-DPT.

Legal Status

  • Germany: DPT 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.
  • Latvia: DPT is a Schedule I controlled substance.
  • New Zealand: DPT is an analogue of DMT, so is a Class C controlled substance in New Zealand.
  • Sweden: Following its sale as a designer drug, DPT was made illegal in Sweden on January 26, 2016.
  • United Kingdom: DPT is a Class A controlled substance in the United Kingdom as a result of the tryptamine catch-all clause.
  • United States: DPT is unscheduled in the United States. It may be considered an analogue of DET, a Schedule I controlled substance 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. DPT is a Schedule I controlled substance in the states of Florida, Maine, and Oklahoma making it illegal to buy, sell, or possess.
