Research Overview
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.
Arginine Vasopressin
Animal and human studies indicate vasopressin can modulate hippocampal and limbic circuits involved in learning and memory. The effect size is context dependent, and results vary by dose, route, and baseline cognitive state.
