Research Overview
Desmopressin
The literature is mixed, but desmopressin has shown memory-related effects in selected populations and experimental paradigms. Its cognitive effects are usually discussed as a vasopressin-pathway probe rather than a primary nootropic.
IGF-2
IGF-2 has strong preclinical evidence for improving memory formation and supporting synaptic changes tied to learning. It also shows neuroprotective and repair-related effects in models of injury and neurodegeneration.
