ACE-083

10 Vials of 1mg ACE-083 Peptide – Lab-tested, high-purity myostatin inhibitor for research. Supports localized muscle growth studies with safe, reliable delivery.

ACE-083 (also known as a modified follistatin-Fc fusion protein) is a locally-acting therapeutic designed to increase muscle mass in specific target areas. Unlike systemic agents, ACE-083 is injected directly into a muscle, where it binds and inhibits myostatin and activin A—key negative regulators of muscle growth. This localized action promotes muscle hypertrophy precisely at the injection site, making it a candidate for treating focal muscle weakness.

Developed by Acceleron Pharma, ACE-083 was studied in conditions like facioscapulohumeral muscular dystrophy (FSHD) and Charcot-Marie-Tooth disease. Clinical trials showed significant increases in muscle volume at the injection site (up to 13–24%)
