Exercise and Weekly Sirolimus (Rapamycin) in Older Adults: RAPA‐EX‐01 Randomised, Double‐Blind, Placebo‐Controlled Trial

Randomized Controlled Trial

Human

2026 Apr

The study gave older adults rapamycin plus exercise and found they didn’t get stronger as much as those on placebo—so rapamycin may have actually reduced the benefits of exercise.

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

Randomized Controlled Trial

Human

2024 Oct 1

The study is testing whether rapamycin plus exercise helps older adults get stronger, but the results aren’t ready yet, so we can’t say if it works or not.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Older mice with overactive mTORC1 had higher levels of certain muscle-related amino acid processes after taking rapamycin, which might help muscles handle stress and stay healthy.

Taking a weekly 6 mg dose of rapamycin might actually slow down strength gains in older people who are working out, even though both those on and off the drug get a bit stronger.
