Where to buy 4-HO-DiPT for sale online


4-Hydroxy-N, N-diisopropyltryptamine, commonly known as 4-HO-DiPT or Iprocin, is a synthetic psychedelic substance. It shares a structural relationship with psilocin, 4-HO-DET, and 4-HO-DPT, a higher homolog of the former and a positional isomer of the latter. Its molecular sub-structure is rooted in the tryptamine class of compounds.

Oral activity for 4-HO-DiPT typically begins at doses of approximately 3 milligrams and above, with effects lasting for approximately 2 to 3 hours. However, when administered at higher doses, such as those exceeding 30 milligrams, the duration of the effects can be significantly extended.


The effects of 4-HO-DiPT share broad similarities with other serotonergic psychedelics like LSD and psilocin, yet they are distinctive due to their relatively brief duration. According to Shulgin, there’s a unique combination of speed, intensity, brevity, and sensitivity to dose in 4-HO-DiPT, particularly when taken orally. A characteristic effect noted by Shulgin is the drug’s tendency to induce tremors.
Users have reported minor audio distortions at lower dosages, with higher doses intensifying these distortions. These auditory distortions manifest as slight changes in pitch and encompass various effects like pitch bending, volume alterations, and rate distortions. As is familiar with many DiPT psychedelics, music may become more dissonant and less harmonious. Additionally, users have described visual distortions akin to those experienced with the hallucinogen LSD.

Clinical trials

FT-104, a prodrug for 4-HO-DiPT, has progressed into the phase 1 clinical trials stage. These trials are double-blind, randomized, and placebo-controlled and are being conducted with the participation of healthy volunteers at the Royal Adelaide Hospital in Australia. These trials aim to explore its potential in treating postpartum depression and treatment-resistant depression.[6][7][8] It is considered a potentially less neurotoxic alternative to compounds like alpha-methyltryptamine (αMT, AMT, Indopan) and alpha-ethyltryptamine (αET, AET, Monase).

Legal status

Regulated by government decree, 4-HO-DiPT is banned from the consumer market.
4-HO-DiPT falls under the jurisdiction of the New Psychoactive Substances Act (NpSG) in Germany. Its use is permitted solely for industrial and scientific purposes.
The health ministry of Sweden’s parliament, Sveriges riksdag, has classified 4-HO-DiPT as a “health hazard” under the Act on the Prohibition of Certain Goods Dangerous to Health (Lagen om förbud mot vissa hälsofarliga varor). This classification came into effect on March 1, 2005, as specified in regulation SFS 2005:26. It is listed as 4-hydroxi-N, N-diisopropyltryptamin (4-HO-DIPT), rendering it illegal to sell or possess.
United States:
At the federal level in the United States, 4-HO-DiPT is not scheduled. However, it could be considered an analog of 5-MeO-DiPT. In such a case, purchase, sale, or possession could be subject to prosecution under the Federal Analog Act.
“4-Hydroxy-N, N-diisopropyltryptamine” is categorized as a Schedule I controlled substance in Florida. Consequently, buying, selling, or possessing this substance in Florida is illegal.
