Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.

Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.

This is an Experimental Substance with little data. This is most likely because the substance is is not very old. Information is limite and incomplete.

Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

25N-NBOMe Also known as:

  • 0G7SSW2N0S
  • 2-(2,5-Dimethoxy-4-nitrophenyl)-N-(2-methoxybenzyl)ethanamin[German][ACD/IUPAC Name]
  • 2-(2,5-Dimethoxy-4-nitrophenyl)-N-(2-methoxybenzyl)ethanamine[ACD/IUPAC Name]
  • 2-(2,5-Diméthoxy-4-nitrophényl)-N-(2-méthoxybenzyl)éthanamine[French][ACD/IUPAC Name]
  • Benzeneethanamine, 2,5-dimethoxy-N-[(2-methoxyphenyl)methyl]-4-nitro-[ACD/Index Name]

A rare, highly potent and yellow psychedelic phenethylamine and derivative of 2C-N. Effects are similar to other NBOMe compounds, with hallucinations, intense body load, stimulation and vasoconstriction. At high doses vasoconstriction can be dangerous, exercise caution.


The name 25N-NBOMe, which short-hand for 2C-N-NBOMe, is a derivative of the phenethylamine psychedelic 2C-N. It was discovered in 2004 by Ralf Heim at the Free University of Berlin and subsequently investigated by a team at Purdue University led by David E. Nichols.

25N-NBOMe has a notably shorter duration than the rest of the 25x-NBOMe series with a total duration of 6 hours and a peak duration of 2 hours. It is moderately active at a dose of one milligram, and two milligrams provide a strong/heavy trip. This substance is considerably less potent when compared to the more popular NBOMe compunds such as 25B-NBOMe, 25I-NBOMe and 25C-NBOMe, all which produce strong experiences at doses above 1mg.

Compounds of the NBOMe family are not orally active and should be administered sublingually by placing and holding it into one’s mouth and allowing it to absorb over a period of 15-25 minutes. This substance had no history of human use before being sold online as a designer drug in 2010. Extremely little is known about the pharmacological properties, metabolism, and toxicity of 25N-NBOMe in humans, and many members of the 25x-NBOMe series have been associated with deaths and hospitalizations.

Along with its highly sensitive dose-response and unpredictable effects, many reports also suggest that this substance may be overly difficult to use safely. Therefore it is highly advised to approach this poorly understood psychedelic substance with the proper amount of precaution and harm reduction practices if using it.




25N-NBOMe is a substituted phenethylamine with methoxy groups CH3O- attached to carbons R2 and R5 as well as a nitro group NO2- attached to carbon R4.

It differs from 2C-N structurally through a substitution on the amine (NH2) with a 2-methoxybenzyl (BOMe) group as shown in the image to the right.

25N-NBOMe shares this 2-methoxybenzyl substitution with other chemicals of the NBOMe family.

This NBOMe addition contains a methoxy ether CH3O- bound to a benzene ring at R2.

Auditory Effects

Psychological Effects

The cognitive effects of 25N-NBOMe can be described as quite reminiscent to that of 25C-NBOMe. They can be broken down into several components which progressively intensify proportional to dosage. These are described below and generally include:

Pharmacological Effects

25N-NBOMe likely has efficacy at the 5-HT2A receptor where it is assumed to act as a partial agonist. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive. There is insufficient scientific research to determine this compound’s true nature as the pharmacological properties of 25N-NBOMe have not been described in the scientific literature, but only in anecdotal reports.

Physical Effects

Sensory Effects

  • Dosage independent intensity - While the reasons for this are not understood, many reports suggest that this substance can produce unexpectedly strong or weak effects even when taken at the seemingly same dose in an unpredictable manner. This may contribute to the relative risk it is poses compared to most other psychedelics.
  • Synaesthesia - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.

Subjective Effects

Disclaimer: The effects listed below are cited from the Subjective Effect Index (SEI), which relies on assorted anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be taken with a healthy amount of skepticism. It is worth noting that these effects will not necessarily occur in a consistent or reliable manner, although higher doses (common+) are more likely to induce the full spectrum of reported effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

Visual Effects




The visual geometry encountered on 25N-NBOMe is often described as similar in appearance to that of LSD. It can be comprehensively described as algorithmic in style, intricate in complexity, fine and zoomed out in detail, fast and smooth in motion, structured in shape, colourful in scheme, glossy in colour, sharp around its edges and mostly rounded across its corners.

In terms of its behaviour, 25N-NBOMe’s geometry leads onto level 8A visual geometry with level 8B remaining so far unconfirmed within this substance. It also seems to consistently build up in visual intensity when the user stares at a central point. This eventually envelops the visual field and creates the sensation that the user has broken through into a continuously shifting geometric landscape or structure with a vast sense of physical size attributed to it.
