Interventions Testing Program
An NIH-funded program run out of three independent labs, considered the most robust scientific tool for testing exogenous molecules for lifespan extension in non-inbred mice; found no benefit for NR or resveratrol.

Peter Attia MD
A set of rigorous, multi-site studies funded by the NIA to test potential longevity-extending molecules in genetically heterogeneous mice, considered the 'gold standard' for longevity drug testing.

204 - Centenarians, metformin, and longevity | Nir Barzilai, M.D.
Peter Attia MD
A highly rigorous study conducted in mice, independently across three labs, known for its all-cause mortality endpoint. Metformin alone did not show strong longevity benefits in ITP, raising questions about species differences or dosing.
