Summary
2,5-Dimethoxy-4-propylthiophenethylamine (also known as 2C-T-7, Blue Mystic, and Beautiful, It is a member of the 2C-x family of psychedelic phenethylamines, all of which were derived from the systematic modification of the mescaline molecule. In contrast to other members of the 2C-x family, 2C-T-7 has gained a reputation of being an unpredictable, dose-sensitive psychedelic capable of producing strong visual effects and an intense body load, which can manifest as a dangerous delirium in extreme cases. Many reports indicate that the physical effects are too severe for inexperienced users or those with pre-existing medical conditions.
Perspectives
“A wonderful day of integration and work. Took about 2 hours for the onset. Some nausea on and off—that seemed to cycle periodically throughout the day. Visuals were great, much like mescaline but less sparkly. Lots of movement and aliveness—velvety appearance and increased depth perception. Neck and shoulder tension throughout the day along with legs. I would periodically notice extreme tightness of muscles, and then relax. Working was very integrative. Back and forth constantly between wonderful God-space—similar to MDMA but more grounded—then always back to sadness. I felt that it really showed me where I was unfinished, but with self-loving and tolerance. Tremendous processing and letting go. Seeing things very clearly and also able to laugh at my trips. Lots of singing. In spite of shoulder tension, vocal freedom and facility were very high. I felt my voice integrated and dropped in a way it never had before, and that remained for several days. Able to merge body, voice, psyche and emotions with music and then let go of it as a role. I also realized and gave myself permission to do whatever it takes to get free. I let go of Dad with tragic arias. The next day I let go of Mom by singing Kaddish for her, and merging with it.”
