Research Overview
Cosyntropin
Cosyntropin is not a standard pain drug, but it appears in headache literature because ACTH analogs can help some patients with difficult migraine attacks. The analgesic rationale is partly tied to steroidogenic and anti-inflammatory effects.
Ibutamoren
Clinical studies show oral ibutamoren reliably elevates GH and IGF-1 over 24 hours with once-daily dosing. Body composition and appetite effects vary by population, and development has been limited by metabolic side effects.
