Summary
2C-T is a lesser-known research chemical with very limited human use history and minimal scientific data on its pharmacology, metabolism, and toxicity. It is structurally similar to 2C-T-2 and 2C-T-7 and may possess MAOI properties, making it potentially more dangerous when combined with other serotonergic substances. The substance is illegal in many jurisdictions including the United States (Schedule I), United Kingdom (Class A), and Canada (Schedule III).
Perspectives
“Poetry was an easy and natural thing. Both the reading of it and the writing of it. This is a potential MDMA substitute since it opens things up but it doesn’t do anything to get in the way.”

A week after trying 2C-T for the first time at a dose of 50mg, I was eager to experience its full effects. I took 100mg and then started to play guitar. After 20 minutes or so, I started noticing the first effects coming on. Things were looking extra colorful and playing guitar was easier than usual.
