The Claim

In adult female mice undergoing progressive weighted wheel running, both frequent (2 mg/kg, 3 times per week) and intermittent (2 mg/kg, once per week) rapamycin dosing impair glucose tolerance compared to vehicle control, with intermittent dosing resulting in less severe glucose intolerance, suggesting a partial protective effect of less frequent administration.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In female mice that run with added weight, taking a drug called rapamycin makes it harder for their bodies to handle sugar — but doing it less often doesn't hurt as much, so spacing out doses might help reduce the downside.

See the scientific wording

In adult female mice performing progressive weighted wheel running, both frequent and intermittent rapamycin dosing (2mg/kg 3x/week or 1x/week) impair glucose tolerance compared to vehicle control, but intermittent dosing results in less severe glucose intolerance, indicating a partial protective effect of less frequent administration.

What the research says

1 study
  1. Study: Rapamycin does not compromise physical performance or muscle hypertrophy after PoWeR while intermittent rapamycin alleviates glucose disruptions by frequent rapamycin

    The study found that giving rapamycin once a week or three times a week made mice less able to handle sugar, but once-a-week caused less harm than three times a week, which matches the claim.
