Important safety remarks: 25I-NBOH is a very new substance, with little known about its pharmacological or behavioral risks. The LD50 (median lethal dose) is not known. Elaborate studies on this substance have not been performed, so long term effects are UNKNOWN! Warning: This chemical is active in the microgram (µg) range! Please use extreme caution if working with this substance, a calibrated milligram scale and liquid measurement are VITAL! Please start with doses of 500µg or less! Warning: Do not ingest 25I-NBOH while under the influence of a second medicine/substance/drug/MAOI! Warning: Do not ingest 25I-NBOH when your mental or physical health is poor. Observe the set and setting!

25I-NBOH (NBOH-2CI, Cimbi-27) is a derivative of the phenethylamine derived hallucinogen 2C-I. It acts as a potent agonist for the 5HT2A receptor, with a Ki of 0.061nM at the human 5HT2A receptor, making it some twelve times the potency of 2C-I itself. In contrast to 25I-NBOMe with a Ki of 0.044 nM (sixteen times the potency of 2C-I). Therefore treat 25I-NBOH like you would treat 25I-NBOMe.

It was discovered in 2006 by a team at Purdue University.

• Activity via sublingual administration or parenteral starts at well below one milligram (full activity at 500-700µg) and may be fatal in high doses!

• Doses lower than one milligram have reported some visual and cognitive activity, though reports are not detailed/well-defined.
