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.

A rare tryptamine psychedelic closely related to DMT, with the interesting property of having little visual hallucinations, but strong auditory effects.


It is a structural analog of DMT and related to various psychedelic tryptamines such as 4-HO-DiPT, 5-MeO-DiPT, and MiPT. The first human trials of DiPT were undertaken in 1975 by Alexander Shulgin, who would co-author and publish a paper detailing its synthesis and human psychopharmacology in 1981. A summary of the synthesis and reports of human use is included in Shulgin's 1997 book TiHKAL ("Tryptamines I Have Known And Loved").

It has been sold online as a research chemical. While most psychedelics are known for producing vivid visual distortions, DiPT’s effects are reported to be primarily auditory in nature. Anecdotal reports have described it causing a downward shift in perceived pitch and other unusual distortions.

It has been suggested that DiPT may have value in neurological research due to its unique effects on auditory perception. Additional subjective effects of DiPT include a body high, moderate euphoria, mild visuals, dizziness, and nausea. Very little data exists about the pharmacological properties, metabolism, and toxicity of DiPT, and it has a limited history of human use.

It is highly advised to use harm reduction practices if using this substance.


Tryptamines share a core structure comprised of a bicylic indole heterocycle attached at R3 to an amino group via an ethyl side chain. DiPT also contains two isopropyl groups bound to the terminal amine RN of its tryptamine backbone.

Isopropyl groups are a three carbon (propyl) chain bound at the middle carbon to the chemical structure.

DiPT has substituted analogues such 5-MeO-DiPT. DiPT is analogous to DMT, containing two isopropyl groups bound at RN instead of the two methyl groups found in DMT.

  • Latvia: DiPT is a Schedule I controlled substance.
  • New Zealand: DiPT is an analogue of DMT, so is a Class C controlled controlled substance in New Zealand.
  • United Kingdom: DiPT is a Class A controlled substance in the United Kingdom as a result of the tryptamine catch-all clause.
  • United States: DiPT is unscheduled in the United States. It may be considered an analogue of DET, a Schedule I compound 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.
    • Florida: DiPT is a Schedule I controlled substance in the state of Florida. It is illegal to buy, sell, or possess.
