Semax and PE-22-28 work through neurotrophic and neurotransmitter pathways; BDNF elevation, serotonin channel modulation, and neurochemical environment optimization. Their cognitive benefits are mediated through the quality of signaling in existing neural networks.
Dihexa targets the physical architecture of the brain by promoting the formation of entirely new synaptic connections; it supports cognitive function by increasing the structural complexity and density of neural networks rather than optimizing how existing ones operate. Patients with goals specifically around learning capacity, memory formation, or neural repair may find Dihexa's structural mechanism addresses a distinct dimension of cognitive health.
