According to Alexander Shulgin in his book PiHKAL (Phenethylamines I Have Known and Loved), Ψ-2C-T-4 produced short-lasting threshold psychoactive effects at doses of 8 to 12 mg.^[1][3][4] Higher doses were not assessed and its effective dose range has not been determined.^[1][3][4] In a subsequent review, Shulgin stated that it was active at doses in the "10 to 20 mg range" but that more study was required to establish its dose range and effects.^[2]

The drug was first described in the scientific literature by Shulgin by 1991 and was further briefly described by him in 2003.^[1][2][3]
