Community reviews of DOM
- calmerin rated it 4/5 - Longer creative flow that survived a demanding work week: After a 10‑week trial of low‑dose STP, I noticed my ability to maintain deep focus on complex data models stretched noticeably longer than usual, even on days packed with meetings and gym sessions. The visual intensity was present but manageable, and the only downside was a mildly restless night after the highest dose.
