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.
Buserelin
Buserelin has been studied extensively as a GnRH agonist in IVF down-regulation and other reproductive-endocrine protocols. Its use helped establish modern cycle-control approaches in assisted reproduction.
