# Eight Hyped Compounds Failed to Extend Lifespan in a Major Mouse Study

- **Evidence Level**: Strong
- **Journal**: GeroScience
- **Sample Size**: UM-HET3 mice across three sites (exact N not specified)

- **Original Source**: https://pubmed.ncbi.nlm.nih.gov/41843349/

## Summary

The NIA's Interventions Testing Program tested eight compounds across three lab sites in genetically diverse mice. None extended lifespan. That includes astaxanthin, alpha-ketoglutarate, pioglitazone, atorvastatin-telmisartan, and others with prior promising results. Some compounds previously shown to work at different doses or start ages didn't replicate under new conditions. Two drugs actually shortened lifespan in female mice.

## Practical Takeaway

This study suggests that dose and timing matter enormously, and early lifespan results in mice often don't hold up.
