Research Overview
C-peptide
C-peptide is not an approved analgesic, but multiple studies have examined its effects on peripheral nerve blood flow and neuropathy outcomes. The strongest relevance is in diabetic neuropathic pain rather than migraine.
Davunetide
Preclinical work showed davunetide can protect neurons, preserve synaptic structure, and improve performance in memory tasks. Human trials largely focused on neurodegenerative disease outcomes rather than stand-alone nootropic use, but the literature supports CNS activity.
