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.
Calcitonin
Calcitonin has been evaluated in randomized trials and reviews for pain associated with vertebral compression fractures and other bone-related conditions. The signal is strongest for short-term analgesia rather than long-term chronic pain control.
