Methylbutyltryptamine (MBT), also known as N-methyl-N-butyltryptamine, is a lesser-known psychedelic drug of the tryptamine family related to dimethyltryptamine (DMT). [1]
MBT was first synthesized by Alexander Shulgin. [1] In his book TiHKAL (Tryptamines I Have Known and Loved), the minimum dose is listed as 250 to 400 mg orally, and the duration listed as 4 to 6 hours. [1] MBT produces a heavy body load with dehydration, and causes visuals similar to those of DMT. [1] Very little data exists about the pharmacological properties, metabolism, and toxicity of MBT. [1]
Analogues of MBT include methylethyltryptamine (MET), methylpropyltryptamine (MPT), methylisopropyltryptamine (MiPT), and methylallyltryptamine (MALT), among others. [1]
TiHKAL mentions that a structural isomer of MBT exists, with the butyl group attached at the nitrogen atom. [1] It is known as N-sec-butyl-N-methyltryptamine, or MSBT. [1] However, little is known about its psychoactivity. [1]
