What is ACE-031?
ACE-031 is a fusion of the extracellular domain of activin receptor IIB with an Fc region. In published research it binds myostatin and related ligands before they reach the receptor, making it a standard tool for probing the myostatin signalling axis.
Mechanism of action
Acts as a decoy receptor sequestering myostatin and related TGF-β family ligands in muscle-mass research models.
Primary research areas
Myostatin pathway inhibition, muscle mass regulation, TGF-β ligand biology.
Research notes
- Non-selective across several TGF-β family ligands, an important consideration in study design.
- Distinct from GH-axis secretagogues, which act upstream of IGF-1 rather than on myostatin.
- Strictly for laboratory research use — not for human or veterinary application.

Patricia ThomasGoogle reviewWas this helpful?Great quality and trusted
Very great service great quality and trusted I've tested the quality
Andrew SiblyGoogle reviewWas this helpful?Results matched the COA reports
Trust is everything when buying research peptides, and this company exceeded my expectations. My order arrived quickly, communication was excellent, and I independently tested the peptides myself. The results matched the COA reports exactly, which gave me complete confidence in the quality and transparency of their products. Highly recommended.
