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.
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.

Psychedelic Phenethylamine, active in the lower microgram range, that is not active orally.
It is a member of the 25x-NBOMe series, a recently discovered group of potent psychedelic compounds derived from the 2C-x family. The name 25B-NBOMe, which is short-hand for 2C-B-NBOMe, indicates it is a derivative of the phenethylamine psychedelic 2C-B. 25B-NBOMe was discovered in 2004 by Ralf Heim at the Free University of Berlin.
It acts as a potent partial agonist for the 5-HT2A receptor. It has been used in clinical trials with an evaluation dose for safety consideration to humans of only 1 microgram. Such a dose was determined to be only 1/300th the dose expected to be hallucinogenic to humans and that recreational use would greatly exceed doses determined to be safe to humans.
This substance had no history of human use before being sold online as a designer drug in 2010. Subjective effects include stimulation, open and closed-eye visuals, time distortion, euphoria, and ego loss. Anecdotal reports suggest 25B-NBOMe to be an active hallucinogen at a dose of as little as 250–500 µg, making it a similar potency to other phenethylamine derived hallucinogens such as Bromo-DragonFLY.
It is worth noting that compounds of the NBOMe class are not orally active and should therefore be taken sublingually by placing them into one’s mouth and allowing it to absorb over a period of 15-30 minutes. Extremely little is known about the pharmacological properties, metabolism, and toxicity of 25B-NBOMe in humans. Numerous members of the 25x-NBOMe series have been associated with hospitalizations and deaths.
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 use harm reduction practices if using this substance.
25B-NBOMe is a substituted phenethylamine with methoxy groups CH3O- attached to carbons R2 and R5 as well as a bromine atom attached to carbon R4.
It differs from 2C-B structurally through a substitution on the amine (NH2) with a 2-methoxybenzyl (BOMe) group.
25B-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.
