Research Overview

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.

Methoxy PEG-Epoetin Beta

Clinical trials show predictable hemoglobin correction with a long dosing interval and sustained red-cell stimulation. Any VO2 max effect would be secondary to higher hemoglobin, not a direct ergogenic mechanism.
