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.
Leuprolide
Leuprolide is one of the best-studied GnRH analogs in reproductive medicine and assisted reproduction. It produces an initial flare followed by receptor desensitization and reduced LH/FSH output.
