Buy Follistatin 315 1mg for Myostatin Inhibition and Muscle Growth Research
What Is Follistatin 315?
Follistatin 315 is a naturally occurring glycoprotein peptide known for its ability to inhibit myostatin (GDF-8) — a protein that negatively regulates muscle growth.
The “315” designation refers to the amino acid length of the mature form of follistatin produced by alternative splicing of the FST gene.
In scientific research, Follistatin 315 is investigated for its potential roles in muscle hypertrophy, tissue regeneration, fertility regulation, and cell differentiation.
How Does Follistatin 315 Work in the Body?
Follistatin 315 functions primarily as a myostatin antagonist. It binds to myostatin molecules and prevents them from attaching to their receptors on muscle cell surfaces (ActRIIB).
This process results in:
-
Enhanced muscle fiber size and density in experimental models
-
Upregulation of muscle protein synthesis pathways
-
Potential promotion of tissue repair and regeneration
-
Suppression of inhibitory cytokines in the myogenic environment
Additionally, Follistatin also interacts with other TGF-β superfamily members such as activins and GDF-11, making it a key regulatory molecule in diverse biological pathways.
