4-HO-MIPT, also known as miprocin, N-isopropyl-nor-psilocin or 4-hydroxy-N,N-methylisopropyltryptamine, is a novel new tryptamine that is most closely related to psilocin and psilocybin.

Recently, a research paper published by the University of Massachussets cited The Indole Shop as a reference for providing them with 4-HO-MiPT as a purity testing standard/analytical sample for research: “Single crystals suitable for X-ray analysis were obtained from the slow evaporation of aqueous solutions of commercial samples of N-methyl-N-iso­propyl­tryptammonium fumarate and 4-hy­droxy-N-methyl-N-iso­propyl­tryptammonium fumarate (The Indole Shop)” (Chadeayne et al.).

This paper confirms not only the authenticity but also the high level of purity of our sample, which is the golden standard of professionalism when providing high-purity chemical samples for our customers.

This product is NOT meant for human consumption and is purely intended for research purposes ONLY, such as purity testing (confirmation of purity with reagent test kits, GC-MS testing, or HNMR). By purchasing you must agree that you are at least 21 years of age or older. Available as the fumarate salt.
