At this point, I strongly believe cycling Cerebrolysin, Dihexa, Semax and Selank has meaningfully increased my effective IQ. The change is not “I feel smarter.” It’s specific: 1. I can rank multiple solutions to a problem in real time, execute the best one, and instantly switch to the next-best path if it fails. 2. I understand the full architecture of something much faster without getting trapped in details, while still retaining the detail map in the background. 3. My social intelligence survives deep work now. After pushing cognition hard for hours, I can still walk into a room, read people quickly, pick up subtle social information and understand them without needing everything explicitly stated. 4. Cognitive intensity no longer cannibalizes emotional intelligence. I can push analytical thinking much harder, retain social/emotional bandwidth, and recover far faster afterward. The biggest change: more forms of intelligence seem to be running in parallel. Previously, maxing out one shut the others down.
