4-Hydroxy-N,N-diisopropyltryptamine, commonly known as 4-HO-DiPT or Iprocin, is a psychedelic substance belonging to the tryptamine class. Similar to psilocin, it induces psychedelic effects upon administration. Structurally, it is the 4-hydroxy analog of DiPT and shares similarities with other tryptamines like 4-HO-DMT (Psilocin), 4-HO-MiPT (Miprocin), and 4-HO-DET (Ethocin).

Exploration of Effects

First synthesized by David B. Repke in 1977, the effects of 4-HO-DiPT in humans were further investigated by Alexander Shulgin. Shulgin detailed its characteristics in his 1997 book "TiHKAL" ("Tryptamines I Have Known and Loved"). Notably, it stands out among psychedelics due to its unique properties: rapid onset (typically within 15 minutes of ingestion), intense effects (even 20 milligrams can induce transcendent experiences), short duration (lasting 2-3 hours), and sensitivity to dosage. Users also reported idiosyncratic physical effects such as muscle tremors and bodily discomfort.

Current Usage and Distribution

Today, 4-HO-DiPT is used for both recreational and entheogenic purposes. However, it remains relatively uncommon and is occasionally available on the online research chemical market. Despite its usage, there is limited knowledge about its pharmacological properties, metabolism, and toxicity in humans, partly due to its restricted history of human consumption. Given these uncertainties, it is strongly advised to practice harm reduction measures when using this substance.

Chemistry of 4-HO-DiPT

4-HO-DiPT, also known as 4-Hydroxy-N,N-diisopropyltryptamine, is a synthetic indole alkaloid belonging to the tryptamine chemical class. Tryptamines share a fundamental structure characterized by a bicyclic indole heterocycle attached at R3 to an amino group through an ethyl side chain. In the case of 4-HO-DiPT, it is further distinguished by a hydroxyl functional group (OH−) at R4 of its indole heterocycle and two isopropyl groups attached to the terminal amine RN of its tryptamine backbone.

Relationship with DiPT and 4-HO-DMT

4-HO-DiPT serves as a 4-hydroxy analog of DiPT and represents the N-substituted isopropyl homolog of 4-HO-DMT.


Serotonergic Psychedelic Properties

Like many psychedelic tryptamines, 4-HO-DiPT is primarily believed to act as a 5-HT2A partial agonist. The psychedelic effects associated with 4-HO-DiPT are thought to stem from its binding efficacy at the 5-HT2A receptors. However, the precise mechanisms of these interactions and how they contribute to the psychedelic experience remain elusive. Further research is needed to fully understand the pharmacological properties of 4-HO-DiPT and its impact on the serotonergic system.

Dosage of 4-HO-DiPT

Understanding the appropriate dosage of 4-HO-DiPT is crucial for safe and responsible use of this psychedelic substance. The following dosage guidelines provide a framework for users to gauge the intensity of their experience.

Threshold Dosage

The threshold dosage for 4-HO-DiPT is noted at 3 mg. At this level, users may start to perceive subtle effects, marking the beginning of the psychedelic experience.

Light Dosage

In the light dosage range of 3 to 10 mg, users can expect a mild to moderate experience. This dosage is suitable for those seeking a gentle introduction to the effects of 4-HO-DiPT, with perceptual changes and a mild alteration of consciousness.

Common Dosage

The common dosage range falls between 10 and 20 mg. At this level, users can anticipate a more pronounced and immersive psychedelic experience. It is a suitable range for those familiar with 4-HO-DiPT and seeking a moderate to strong effect.

Strong Dosage

For a stronger psychedelic encounter, individuals may choose a dosage between 20 and 30 mg. This range is characterized by intensified effects, potentially leading to a more profound and transformative experience.

Heavy Dosage

Dosages exceeding 30 mg are considered heavy. At this level, users should be prepared for a significantly intense and immersive psychedelic journey. Heavy dosages of 4-HO-DiPT may induce profound alterations in perception and consciousness.

It is essential for users to approach 4-HO-DiPT with caution and adhere to harm reduction practices. Understanding individual tolerance and sensitivity is crucial, and users are encouraged to start with lower doses before gradually increasing if needed. Additionally, having a trusted and sober companion can contribute to a safer and more positive experience.

Subjective Effects of 4-HO-DiPT

Understanding the subjective effects of 4-HO-DiPT is essential for individuals considering its use. However, it is crucial to approach the information with a degree of skepticism, as the effects can vary among users. The Subjective Effect Index (SEI) serves as a reference, relying on anecdotal user reports and analyses from contributors to PsychonautWiki.


Before delving into the subjective effects, it is important to acknowledge the limitations of the SEI. The information is based on open research literature and anecdotal experiences, which may not guarantee predictability or reliability in individual cases. Higher doses are more likely to induce a full spectrum of effects, but adverse reactions, including addiction, severe injury, or death, become increasingly probable with elevated doses.

Toxicity and Harm Potential of 4-HO-DiPT

The toxicity and long-term health effects of recreational 4-HO-DiPT use have not been scientifically studied due to its status as a research chemical with minimal human usage history. This article aims to provide an overview of potential harm and safety considerations based on anecdotal reports.

Lack of Scientific Studies

As of now, there is no scientific context for studying the toxicity or long-term health effects of 4-HO-DiPT. The exact toxic dose remains unknown, and caution is advised due to its limited history of human usage.

Anecdotal Reports

Anecdotal reports from individuals who have tried 4-HO-DiPT suggest that at low to moderate doses, used sparingly, there are no notable negative health effects. However, it is essential to recognize that individual reactions can vary, and nothing can be entirely guaranteed.

Harm Reduction Practices

To mitigate potential risks, it is strongly recommended to employ harm reduction practices when using 4-HO-DiPT. Independent research should be conducted to ensure the safety of combining it with other substances.

Tolerance and Addiction Potential

4-HO-DiPT is not considered habit-forming, and the desire to use it may decrease with regular consumption. Tolerance to its effects develops almost immediately after ingestion, taking approximately 3 days for a 50% reduction and 7 days to return to baseline in the absence of further consumption. Cross-tolerance with other psychedelics is reported, meaning a reduced effect after consuming 4-HO-DiPT.

Dangerous Interactions


Combining 4-HO-DiPT with certain substances can be dangerous or life-threatening. Known dangerous interactions include:

  • Lithium: Increased risk of psychosis and seizures, particularly dangerous for those with bipolar disorder.
  • Cannabis: Unpredictable synergy with 4-HO-DiPT, potentially increasing the risk of adverse psychological reactions.
  • Stimulants: Elevated risk of anxiety, paranoia, panic attacks, thought loops, mania, and psychosis.
  • Tramadol: May lower the seizure threshold, potentially triggering seizures in susceptible individuals.

Always conduct independent research to ensure the safety of combining 4-HO-DiPT with other substances.

Legal Status

The legal status of 4-HO-DiPT varies by country:

  • Germany: Controlled under the NpSG (New Psychoactive Substances Act).
  • Sweden: Classified as a "health hazard," making it illegal to sell or possess.
  • Switzerland: Not controlled under specific categories, potentially considered legal.
  • United Kingdom: Class A drug due to the tryptamine catch-all clause.
  • United States: Unscheduled but could be considered an analogue of psilocin, a Schedule I drug.
  • Florida (USA): Schedule I controlled substance, illegal to buy, sell, or possess.
