2C-T-21

2C-T-21 is a psychedelic phenethylamine of the 2C family. It was first synthesized by Alexander Shulgin, sometimes used as an entheogen. It was the first psychedelic drug known to contain six different chemical elements in the structure.

Chemistry

The full name of 2C-T-21 is 4-(2-fluoroethylthio)-2,5-dimethoxyphenethylamine.

Dosage

In his book PiHKAL (Phenethylamines i Have Known And Loved), Shulgin lists the dosage range as 8–12 mg.

Effects

2C-T-21 is generally taken orally, and effects typically last 7 to 14 hours. The potential psychotherapeutic applications of this chemical were explored by Myron Stolaroff who found it a very promising substance in his experiments.

Pharmacology

The mechanism that produces 2C-T-21’s hallucinogenic and entheogenic effects has not been specifically established, however it is most likely to result from action as a 5-HT_2A serotonin receptor agonist in the brain, a mechanism of action shared by all of the hallucinogenic tryptamines and phenethylamines for which the mechanism of action is known. Based on the relatively high potency of 2C-T-21, it is likely that this compound binds quite strongly to the 5HT_2A receptor target.
