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.

Pemvidutide

Clinical studies have reported dose-dependent weight loss and favorable effects on liver fat and transaminases. It remains investigational and is not approved for obesity treatment.
