A Captivating Tryptamine Compound Discovered by Alexander Shulgin

Important Note: 4-HO-DiPT is NOT for Human Consumption. For Laboratory Reagent or Forensic Analysis ONLY.

4-HO-DiPT, also known as 4-hydroxy-N,N-diisopropyltryptamine or iprocin, is a fascinating and lesser-known psychedelic substance within the tryptamine class. It shares structural similarities with tryptamines like 4-HO-DMT (Psilocin), 4-HO-MiPT (Miprocin), and 4-HO-DET (Ethocin).

CAS# 132328-45-1
CAS Name: 3-[2-(diisopropylamino)ethyl]-1H-indol-4-ol
Molar mass:260.381 g·mol−1

Characteristics and Effects

First synthesized by David B. Repke in 1977, 4-HO-DiPT caught the attention of Alexander Shulgin, who explored its effects in humans. Notable for its speed (15 minutes after ingestion), intensity (a mere 20 milligrams can induce a transcendent peak experience), and brevity (2-3 hours), it also presents unique physical effects like muscle tremors and bodily malaise.

Applications and Limited Knowledge

While 4-HO-DiPT is occasionally used for recreational and entheogenic purposes, it remains relatively uncommon. Available as the fumarate salt, it is occasionally distributed on the online research chemical market. However, its pharmacological properties, metabolism, and toxicity in humans are still poorly understood due to its limited history of human use.

Responsible Usage and Harm Reduction

Caution: We emphasize that 4-HO-DiPT is strictly intended for laboratory reagent or forensic analysis purposes. When researching this compound, it is vital to prioritize safety and implement harm reduction practices. Responsible usage within approved and controlled settings is essential to better comprehend its potential effects and characteristics.
