The Claim
In healthy women aged 50–85, intermittent weekly administration of 10 mg compounded rapamycin over 48 weeks likely results in an increase in lean tissue mass compared to placebo, with a mean increase of 6.19% (95% CI: 0.88–11.51), suggesting a potential sex-specific benefit for muscle preservation during aging.
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.
Taking a low weekly dose of a drug called rapamycin for a year might help older women build more lean muscle, which could slow down muscle loss as they age.

What the research says
1 studyStudy: Influence of rapamycin on safety and healthspan metrics after one year: PEARL trial results
The study gave women a weekly rapamycin pill for a year and found they gained more lean muscle compared to those who didn’t, especially at the 10 mg dose. This matches the claim that it helps preserve muscle in older women.
