4-HO-DiPT is also known as Iprocin and 4-hydroxy-N,N-diisopropyltryptamine. Some street names include Ho-Dipped, Tangerine, Jitter, Phour, and Aura. It is a psychedelic tryptamine derivative that is a close structural analogue of psilocin. Alexander Shulgin (2009) wrote that he doubts “there is another psychedelic drug, anywhere, that can match this one for speed, for intensity, for brevity, and sensitive to dose, at least one that is active orally”. Nonetheless, Jebadurai (2013) described the effects of  4-HO-DiPT as “comparatively mild”, emphasizing that users reported that 4-HO-DiPT induced only “mild psychedelic effects”.

Side Effects & Adverse Reactions:

4-HO-DiPT is a very new substance, and little is known about its side effects, adverse reactions, long term damage, and/or addiction potential. According to Jebadurai (2013), some of the negative effects reported by recreational users include:

  • Severe nausea 
  • Hypertension 
  • Constant clenching of muscles throughout the body 
  • Insomnia 
  • Headache 
  • Tremors 
  • Sudden loss of consciousness

Remember, research chemicals are experimental chemicals that are not approved for human consumption. This is because not enough data exists currently about their effects in humans. Although some people are willing to ingest the research chemical 4-HO-DiPT, it is unreasonable to assume that it is in any way safe to use recreationally.
