A recombinant isoform of follistatin, a natural inhibitor of myostatin, studied for its potential to increase muscle mass. Most human work uses gene therapy rather than the injected protein.
Mechanism under study
Follistatin binds and neutralizes myostatin (GDF-8) and activin, releasing a natural brake on muscle growth; this pathway is a target in muscular-dystrophy and muscle-wasting research.
Research-reported dosing
No established human dosing for the injected protein; most human research uses AAV gene therapy delivering follistatin. Research-community injectable use is unvalidated.
Dosing figures describe how this compound appears in the research literature and research-community references. They are not a recommendation for human use.
