The Claim
Rapamycin administration initiated at 600 days of age increases maximum lifespan, defined as age at 90th percentile mortality, by approximately 14% in female mice and 9% in male mice compared to control mice not receiving rapamycin.
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.
Giving old mice the drug rapamycin when they're about 600 days old helps them live longer - female mice lived about 14% longer and male mice about 9% longer than mice that didn't get the drug.
See the scientific wording
Maximum lifespan, measured as age at 90th percentile mortality, is increased by approximately 14% in female mice and 9% in male mice fed rapamycin starting at 600 days of age compared to control mice.
What the research says
1 studyStudy: Rapamycin fed late in life extends lifespan in genetically heterogeneous mice
The study tested exactly what the claim says - feeding rapamycin to mice starting at 600 days old - and found the same results: a 14% lifespan increase in female mice and 9% in male mice when measured at age at 90% death.
