Chemistry:5-MeO-MsBT
5-MeO-MsBT, also known as 5-methoxy-N-methyl-N-sec-butyltryptamine, is a psychedelic drug of the tryptamine and 5-methoxytryptamine families.[1][2] It emerged as a novel designer drug online in December 2022.[1] More specifically, its chemical synthesis and the claimed properties and effects of 5-MeO-MsBT were posted on a specialized psychoactive drug forum.[1]
The dose of the drug is said to be 10 to 30 mg orally and its duration is said to be 3 to 4 hours.[1] Its effects were reported to include a tryptamine-like warmth or fuzzy feeling, tactile and music enhancement, enhanced mood, confusion, mild paranoia, weak psychedelic effects and self-detachment at higher doses, and an antidepressant-like psychedelic afterglow.[1] The afterglow is said to last 12 to 24 hours, with apparent tolerance developing to it with repeated administration over a few days.[1] 5-MeO-MsBT's effects were described as very similar to those of 5-MeO-MiPT at lower doses, but it is less potent than 5-MeO-MiPT and was regarded as inferior in many respects.[1]
The drug has not otherwise been encountered, for instance sold online or in drug seizures, as of 2023.[1] It is not a controlled substance in Canada as of 2025.[3] The drug is not an explicitly controlled substance in the United States,[4] but could be considered a controlled substance under the Federal Analogue Act if intended for human consumption.
