4-HO-MiPT Fumarate

What is 4-HO-MiPT?

4-Hydroxy-N-methyl-N-isopropyltryptamine (also known as 4-HO-MiPT, and Miprocin) is a novel psychedelic substance of the tryptamine class that produces psilocybin-like psychedelic effects when administered. It is part of a series of psychedelic substituted tryptamines such as 4-AcO-DMT, 4-HO-MET, 4-HO-DiPT that are considered to produce variations of the core psychedelic effects typified by psilocin.
This substance is relatively uncommon and has only a short history of human use. Alexander Shulgin evaluated its activity in humans in 1979, describing a trial of 12mg as a richly insightful and highly erotic experience. A description of 4-HO-MiPT is included in Shulgin’s 1997 book TiHKAL. Shulgin’s trials and other anecdotal reports suggest that 4-HO-MiPT is similar in activity to psilocin, the active component in psilocybin mushrooms.

Chemical Properties of 4-HO-MiPT

4-HO-MiPT is a synthetic indole alkaloid molecule of the tryptamine class. Tryptamines share a core structure comprised of a bicylic indole heterocycle attached at R3 to an amino group via an ethyl side chain. 4-HO-MiPT is substituted at R4 of its indole heterocycle with a hydroxyl (HO) functional group OH-. It also contains a methyl group and an isopropyl chain bound to the terminal amine RN of its tryptamine backbone (MiPT). 4-HO-MiPT is the N-substituted isopropyl homologue of 4-HO-DMT (Psilocin)

What are the Effects of 4-HO-MiPT?

4-HO-MiPT’s psychedelic effects are believed to come from its efficacy at the 5-HT2A receptor as a partial agonist. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

4-HO-MiPT has many overlapping effects with substances like 1P-LSD and 4-HO-MET.

Some of the most commonly reported effects of 4-HO-MiPT are: 

  •     Stimulation
  •     Spontaneous bodily sensations
  •     Physical euphoria
  •     Visual hallucinations 
  •     Increased music appreciation
  •     Colour enhancement
  •     Emotion enhancement
  •     Cognitive euphoria

  •     Nausea
  •     Muscle contractions
  •     Thought loops
  •     Feelings of impending doom
  •     Increased salivation
  •     Delusion

I have made several orders at this store. Once the package was not delivered to me. Probably the loss of the carrier that delivered the package. Even though the package was not insured against loss, I was sent compensation in the form of a "gift" in the next order. When I pointed it out. The CC team communicates by e-mail, is happy to advise you and always accommodates your requests. The only e-shop that has soul and very good heart. Great shop, great team. Thank you very much.

I felt this tryptamine as a bit more aggressive than 4 HO-MET and 4 ACO-MET. Increased sense of humor, enhanced color perception, very good for sex, but not for dancing. I felt the music well, but kind of out of me , colder. Couldn’t relax like with methocine and methacetin. It affected me primarily as a stimulant. I also found it quite difficult to speak with a normal pronunciation. This was at the 50mg dose.

Mystical, heroic, nice body load

Very potent product, with a loooot of visuals !
Take very care about the dosage, a 70kg rat should take a maximum of 15~20mg (oral) for a really good trip, while taking a bit more is very stressfull for him and too aggressive for his eyes !
So invest in a 0.001g scale and/or dissolve it in a liquid to take it as drops 😉
(Warning, the taste is disgusting)

Tuvimos una persona voluntaria a experimentar con 4-ho-mipt, a continuación dejo su propio testimonio escrito.

¡Hola! he vivido un viaje espectacular!!! a las15 minutos de la ingesta ya empezaron efectos visuales fuertes. Tuve un viaje muy profundo tipo ayahuasca mezclado con lsd y setas de psilocibina. ¡El proceso duró 15 horas! los efectos visuales internos y externos fueron muy fuertes!! fue muy reconfortante!! comprendí muchos aspectos de mi vida! ¡Gracias!! Recomendado solo para usuario experimentados.

Excellent tryptamine, as well with the 4-HO-MET.
This Miprocin have few differences :
The headspace is more deep and experience can be more introspective than 4-HO-MET.
In term of bodyhigh, this one is very relaxing, warm and sometimes “stoning” in a very good way. Pretty cosy.
Excellent feelings on this side.
The visuals effects are less neonish and feels less synthetic than Metocin, they are even quite present even at common doses, but they feels way more organics, earthy, and natural.
Another excellent tryptamine, kinda short lasting aswell with 4-HO-MET, overall a different but very interesting experience.
Very worth trying too.

Fantastic tryptamine. It’s dosage is forgiveable, small doses will put a smile on your face . Gives one the urge to explore nature, or playing with your pet is very enjoyable. Visuals are there, but the headspace is very gentle and focussed, as is the bodyhigh stimulated to do things, but still relaxed and good feeling. Comfortable and slightly energetic, euophoric, clearheaded, not to overwhelming visuals.

High doses get very intense visually, OEV’s came in waves. With eyes closed (CEV’s) I experienced a profound introspective alternative life. Compared with many people, animals, plants and entities morphing in and out of vision.

4-HO-MiPT is just a fantastic tryptamine with a lot of potential since a ‘sweetspot’ dose. Even at high doses the mind is still very well controlable and the body relaxed.
The visuals are universally tryptamine ‘alien-like’. Morphing patterns of flowers, animals, and ancient Mayan-like art. Very colourful, yet with shades of palette colour, even dark, and bright fluorescent outlines.
