25C-NB3OMe

C30-NBOMe (also known as 30C-NBOMe or 25C-NB345OMe) is structurally distinct from typical NBOMes due to its 3,4,5-trimethoxybenzyl group (mescaline-like pattern) rather than the standard 2-methoxybenzyl group. Despite being theoretically related to active NBOMe compounds, extensive anecdotal evidence from 2013-2016 indicates this substance produces minimal to no psychoactive effects at doses ranging from micrograms to hundreds of milligrams across multiple routes of administration. Only one isolated positive report exists amid numerous reports of complete inactivity. Material sold as C30-NBOMe may be an inert compound, a mislabeled substance, degradation products, or simply inactive due to its unusual chemical structure. The substance is not documented in major harm reduction databases (PsychonautWiki, TripSit).

Also known as: 30c-nbome, 2c-c-nb3ome, Nb3ome-2c-c, 25c-nb345ome
