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.
Elamipretide
Clinical and translational studies show elamipretide can improve mitochondrial function and some functional endpoints in mitochondrial disorders. Skeletal muscle research suggests benefits are driven by energy metabolism rather than direct muscle-building effects.
