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.

REGN1033

Human and animal studies indicate that myostatin neutralization can increase muscle size, though functional gains are often smaller than mass gains. Trevogrumab is part of the broader literature showing that selective myostatin inhibition can alter body composition in clinically meaningful ways.
