4-Thiosymbescaline (4-TSB), also known as 3,5-diethoxy-4-methylthiophenethylamine, is a chemical compound of the phenethylamine and scaline families related to mescaline.[1][2][3][4] It is the analogue of symbescaline in which the methoxy group at the 4 position has been replaced with a methylthio group.[1][2][3][4] The compound is one of two possible thiosymbescaline (TSB) positional isomers, the other being 3-thiosymbescaline (3-TSB).[1][2][3][4]

In his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin lists 4-TSB's dose as greater than 240 mg orally and its duration as unknown.[1][2][3] The effects of 4-TSB have been reported to include a "real effect" and a little spaciness at 80 mg orally, twinges at 160 mg orally, and "no effects at all" at 240 mg orally.[1] It was concluded that the compound is probably inactive.[1]

The chemical synthesis of 4-TSB has been described.[1][4]

4-TSB was first described in the scientific literature by Shulgin and Peyton Jacob III in 1984.[4] Subsequently, it was described in greater detail by Shulgin in PiHKAL in 1991.[1]
