What Is FST 344?

FST 344, or Follistatin 344, is a research peptide derived from the naturally occurring follistatin protein. Follistatin is a glycoprotein found in many tissues throughout the body and is known for its ability to regulate members of the transforming growth factor-beta (TGF-β) superfamily. The FST 344 isoform consists of 344 amino acids and serves as the precursor to the circulating FST 315 form after post-translational processing.

One of the primary reasons FST 344 has gained attention in scientific research is its interaction with myostatin (GDF-8) and activins. Myostatin acts as a negative regulator of skeletal muscle growth by limiting muscle cell proliferation and differentiation. FST 344 binds to myostatin, reducing its biological activity and allowing researchers to investigate the pathways involved in muscle development and regeneration. In addition to myostatin, FST 344 also binds to activins, proteins involved in processes such as cell growth, inflammation, tissue repair, and reproductive biology. Because of these interactions, FST 344 is frequently used to explore complex signaling mechanisms in laboratory settings.

Current research involving FST 344 spans several areas of biomedical science. Scientists use the peptide in preclinical studies focused on skeletal muscle physiology, muscle wasting disorders, regenerative medicine, tissue engineering, and the molecular biology of TGF-β signaling. Researchers are also investigating follistatin’s role in fibrosis, metabolic regulation, and cellular differentiation to better understand its potential applications in future therapeutic development. These studies are conducted in controlled laboratory environments using experimental models rather than in approved clinical settings.
