2C-T-4, also known as 4-isopropylthio-2,5-dimethoxyphenethylamine, is a psychedelic phenethylamine of the 2C family. It was first synthesized by Alexander Shulgin and is used as entheogenic recreational drug.

Effects

2C-T-4 produces psychedelic and entheogenic effects that develop slowly and can last 12 to 18Template:Nbsphours. While users may experience virtually no effects for the first hour after ingestion, results vary drastically between individuals and range from hallucination and euphoria to intense sickness and anxiety. Shulgin devoted a chapter in the first part of his book PiHKAL to this compound, describing an intense "plus-four" psychedelic experience mediated by a twelve milligram dose.

Interactions

2C drugs are metabolized by the monoamine oxidase (MAO) enzymes MAO-A and MAO-B. Monoamine oxidase inhibitors (MAOIs) such as phenelzine, tranylcypromine, moclobemide, and selegiline may potentiate the effects of 2C drugs. This may result in overdose and serious toxicity.

2C-T-4 acts as a serotonin 5-HT₂ receptor agonist, including of the serotonin 5-HT_2A receptor. The mechanism that produces 2C-T-4's hallucinogenic and entheogenic effects has not been specifically established, however it is most likely to result from 5-HT_2A receptor activation in the brain, a mechanism of action shared by all of the hallucinogenic tryptamines and phenethylamines for which the mechanism of action is known.

Chemistry

2C-T-4 is the 2-carbon homolog of Aleph-4. The full chemical name is 2-[4-(isopropylthio)-2,5-dimethoxyphenyl]-ethanamine. The drug has structural and pharmacodynamic properties similar to 2C-T-7 and 2C-T-19.

Homologue

File:Psi-2C-T-4.png

Ψ-2C-T-4, the homologue of 2C-T-4.

2C-T-4 has a homologue, the structural isomer Ψ-2C-T-4 (2,6-dimethoxy-4-(i)-propylthiophenethylamine). This compound was tested by Alexander Shulgin at a dose of 12 mg.

At this dosage its duration was very short and it produced few effects, however based on the research into the better characterized compound Ψ-DOM, the potency of Ψ-2C-T-4 is likely to be around 1/3 that of 2C-T-4 itself, so a more effective dosage of Ψ-2C-T-4 might be in the region of 20–60 mg; however high doses such as this might well be associated with toxic side effects, and so extreme caution would be advised.

Society and culture

Popularity

2C-T-4 is relatively unknown on the black market, but has been sold to a limited extent on the research chemical market.
