Rapamycin is arguably the most interesting longevity drug in preclinical research. It extends lifespan in mice more consistently than any other compound tested. However, human longevity data does not yet exist. The drug has FDA approval for transplant immunosuppression, and off-label longevity use carries real risks including immunosuppression and metabolic side effects.

The full evidence review — including why the most promising longevity drug in mouse research isn't ready for your medicine cabinet — is in Section 2 (Supplements & Compounds) of The Anti-Longevity Playbook.
