What it's actually good for
How it works
Primarily investigated as a gene therapy for muscular dystrophy to inhibit myostatin. There is no robust clinical evidence supporting its use for muscle hypertrophy in healthy humans.
Binds to and neutralizes myostatin, a protein that limits muscle growth, potentially allowing for increased muscle mass.
Safety
- Unknown long-term safety profile in healthy humans
- Risk of off-target organ growth including the heart
- High prevalence of counterfeit or mislabeled products
