There’s a few to choose from… which would you say is the best field or stack for learning and memory? Personally I would be using it for language learning, but also learning new skills in general. (my main concern with using all of them, is simply overdoing it - since most of them seem to use BNDF and NGF)
Nerve Growth Factor (targeted to brain & nervous system)
Permanent Brain Enhancement
Superhuman Genius
Cognitive Enhancement
Enhanced Brain Hemisphere Connectivity
Brain Regeneration
