How ACE-031 Works for Muscle Growth

Sequesters myostatin and related proteins that limit muscle development.

About Muscle Growth

Enhancement of muscle protein synthesis and lean muscle mass development.

Research Evidence

Phase II trials in Duchenne MD showed significant muscle mass increase but were halted due to nosebleeds and gum bleeding. The broad ligand binding may cause unwanted vascular effects.

Clinical Status:Development halted - Safety concerns
