4-MeO-MiPT, also known as 4-methoxy-N-methyl-N-isopropyltryptamine, is a relatively obscure psychedelic substance. It represents the 4-methoxy counterpart to MiPT. This compound was initially synthesized by Alexander Shulgin and is documented in his book “TiHKAL” (Tryptamines I Have Known And Loved).
In human trials conducted by Shulgin, an effective dose of 20-30 mg (equivalent to 0.4 mg per kg of the subject’s body weight) was established. The onset of effects typically occurred 45-60 minutes after ingestion, with the sensations lasting for approximately 2-2.5 hours. Unlike some other tryptamines, 4-MeO-MiPT was noted for its relatively milder effects, focusing on enhancing erotic experiences and fewer visual hallucinations.
However, it’s important to note that there is limited available data regarding the pharmacological properties, metabolic processes, and potential toxicity associated with 4-MeO-MiPT.
