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.
Ipamorelin
Ipamorelin has moderate clinical evidence. Phase II trials demonstrate selective GH release. Generally regarded as one of the safest GH secretagogues with minimal side effect profile.
