2C-T-13 (2,5-dimethoxy-4-(β-methoxyethylthio)phenethylamine) is a psychedelic phenethylamine of the 2C family. It was presumably first synthesized by Alexander Shulgin and reported in his book PiHKAL.[1]


The drug has structural properties similar to mescaline and other drugs in the 2C-T series, with the most closely related compounds being 2C-T-7 and 2C-T-21.

General information

The dosage range of 2C-T-13 is typically 25 - 40 mg and its duration is approximately 6–8 hours according to Shulgin.[1] 2C-T-13 produces many closed-eye visuals and geometric patterns. It also produces slight visual distortion.[1]

The mechanism that produces 2C-T-13's hallucinogenic and entheogenic effects has not been specifically established; however, it is most likely to result from action as a 5-HT2A 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.


The toxicity of 2C-T-13 is not well documented. 2C-T-13 is slightly less potent than 2C-T-7, but it may be expected that at higher doses it would display similar toxicity to that of other phenethylamines of the 2C-T family.


2C-T-13 is not scheduled in the United States, but possession and sales of 2C-T-13 could be prosecuted under the Federal Analog Act because of its structural similarities to 2C-T-7.

As of October 31, 2016, 2C-T-13 is a controlled substance (Schedule III) in Canada.[2]
