2C-T-25, also known as 4-isobutylthio-2,5-dimethoxyphenethylamine, is a serotonin receptor modulator of the phenethylamine and 2C families.^[1][2][3][4] It shows affinity for serotonin receptors and other targets and acts as a potency partial agonist of the serotonin 5-HT_2A and 5-HT_2B receptors.^[4] The dose of 2C-T-25 in humans is unknown.^[5] Daniel Trachsel reported that 2C-T-25 was inactive at doses of up to 30 mg orally.^[1] The drug was first described in the scientific literature by Trachsel in 2003 and was subsequently described further by Trachsel and colleagues in 2013 and 2018.^[1][2][3][4] It is a controlled substance in Canada under phenethylamine blanket-ban language.^[6]
