2C-T-15 or 2,5-dimethoxy-4-(β-cyclopropylthio)phenethylamine is a psychedelic phenethylamine of the 2C family. It was presumably first synthesized by Alexander Shulgin and reported in his book "PiHKAL (Phenethylamines i Have Known And Loved)".


2C-T-15 is the 2 carbon homologue of Aleph-15, which has not been synthesized. The full chemical name is 2- [4-(2-cyclopropylthio)-2,5-dimethoxyphenyl] ethanamine. The drug has structural properties similar to 2C-T-2 and other drugs in the 2C-T series.

General Information

The dosage range of 2C-T-15 is typically 30 mg or more. Its duration is unspecified by Shulgin, and its [http://www.erowid.org/library/books_online/pihkal/pihkal047.shtml entry in PiHKAL] says it lasts for "several hours." [CitePiHKAL] The effects are not prominent, and 2C-T-15 is not very potent.


The mechanism that produces 2C-T-15’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-15 is not well documented. 2C-T-15 is much less potent than 2C-T-7, but it may be expected that at very high doses it would display similar toxicity to that of other phenethylamines of the 2C-T family. Other phenethylamine derivatives substituted with an alkylthio group at the 4 position such as 2C-T-7 and 4-MTA are known to act as selective monoamine oxidase A inhibitors, a side effect which can lead to lethal serotonin syndrome when they are combined with stimulant drugs. Most confirmed fatalities involving 2C-T drugs involve their combination with other hard drugs such as alcohol, ecstasy or cocaine.


2C-T-15 is not illegal, but possession and sales of 2C-T-15 could be prosecuted under the Misuse of Drugs act in the UK or the Federal Analog Act in the US because of its structural similarities to 2C-T-7.
