The Claim
Intermittent rapamycin administration at a dose of 2 mg/kg every 5 days, initiated at 20 months of age in mice, results in increased median and maximum lifespan while preserving glucose homeostasis, indicating that the beneficial effects of rapamycin can be separated from its adverse effects through modified dosing schedules.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
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 less often (every 5 days instead of daily) at a specific dose helps them live longer without causing diabetes-like problems, showing that we might be able to get the good anti-aging effects without the bad side effects.
See the scientific wording
Intermittent rapamycin dosing (2mg/kg every 5 days) beginning at 20 months of age in mice can increase both median and maximum lifespan without detrimental effects on glucose homeostasis, suggesting that benefits can be separated from side effects through alternative dosing schedules.
What the research says
1 studyStudy: Transient and late-life rapamycin for healthspan extension
The study tests whether giving rapamycin intermittently (not continuously) later in life can extend lifespan and healthspan, which matches the claim's idea. However, the abstract doesn't confirm the exact dose (2mg/kg every 5 days at 20 months) used in the claim, so we can't be 100% certain it's the same protocol.
