2C-T-3

2C-T-3, also initially numbered as 2C-T-20 and also known as 4-methallylthio-2,5-dimethoxyphenethylamine, is a lesser-known psychedelic drug related to compounds such as 2C-T-7 and 2C-T-16. It was named by Alexander Shulgin but was never made or tested by him, and was instead first synthesised by Daniel Trachsel some years later. It has a binding affinity of 11nM at 5-HT_2A and 40nM at 5-HT_2C. It is reportedly a potent psychedelic drug with an active dose in the 15–40 mg range, and a duration of action of 8–14 hours, with visual effects comparable to related drugs such as methallylescaline. 2C-T-3 is a controlled substance in Canada under phenethylamine blanket-ban language.
