Myostatin, also called growth differentiation factor 8 (GDF8), is a signaling protein in the TGF-beta superfamily. Researchers investigate its role in regulating skeletal muscle mass and the cellular pathways involved in muscle biology.
Studying selective myostatin inhibition
Trevogrumab (REGN1033) is a monoclonal antibody studied for selective binding to myostatin. Myostatin inhibitor research can examine how neutralizing this ligand affects downstream signaling, in contrast to approaches that interact with multiple ligands in the ActRIIB pathway.
Research methods include cell-based Smad2/3 signaling assays and direct binding measurements. These investigate distinct questions: a functional signaling response versus antibody–ligand binding. This overview does not establish batch-specific potency or testing results for a catalog vial.

The Heritage catalog also includes Myostatin HMP (GDF8) 5 mg. It is a separate research material, not interchangeable with the Trevogrumab antibody. Review each listing’s identity and research context independently.
