The Claim

In adults aged 65–85, once-weekly administration of 6 mg sirolimus (rapamycin) in combination with a 13-week home-based exercise program may improve lower body muscle strength and endurance, as assessed by the 30-Second Chair-Stand Test, although the effect size and clinical significance are uncertain due to the small sample size (n=40) and short trial duration.

Source: A single-center, double-blind, randomized, placebo-controlled, two-arm study to evaluate the safety and efficacy of once-weekly sirolimus (rapamycin) on muscle strength and endurance in older adults following a 13-week exercise program

In plain English

Taking a weekly low dose of a drug called rapamycin while doing a 13-week home exercise program might help older adults (65–85 years old) get stronger legs — but we’re not totally sure how much it helps because the study was small and short.
