2C-T-4
2C-T-4 is a synthetic psychedelic of the substituted phenethylamine and 2C-x families. First described by Alexander Shulgin and colleagues in 1991 and later detailed in his book PiHKAL, it is an orally administered research chemical. Compared to more commonly encountered members of the 2C-T-x series such as 2C-T-2 and 2C-T-7, it is distinguished by a notably longer onset and duration of effects.
