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.
Anamorelin
Trials in cachexia populations showed increased appetite and modest gains in body weight and IGF-1. Regulatory progress has varied by region, but it remains a well-studied ghrelin agonist in the GH space.
