The Claim
In old male mice, a 4-week treatment with an anti-myostatin antibody (ATA 842) increases lean body mass by approximately 7% and grip strength by about 20%.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In aged male mice, a 4-week injection of an anti-myostatin antibody increases lean body mass by 7% and grip strength by 20%.
See the scientific wording
In old male mice, a 4-week treatment with an anti-myostatin antibody (ATA 842) increased lean body mass by approximately 7% and grip strength by about 20%, suggesting that myostatin inhibition can reverse age-related muscle loss and improve physical function in aged mammals.
A protein that normally stops muscle growth is blocked, allowing muscle cells to make more protein and get bigger. Larger muscles can produce more force, which improves grip strength.
What the research says
1 studyIn older male mice, a special injection that blocks a protein called myostatin made their muscles 7% bigger and their grip 20% stronger in just four weeks — exactly what the claim says.
