Plain-English checks of anti-aging drugs, peptides, supplements, tests and treatments—without turning early science into a promise.
Many longevity health claims start with real biology, then overstate what has been proved in people. Use these checks to separate a plausible mechanism or biomarker from evidence of meaningful human benefit, while keeping risk and approval status visible.
This index covers health and anti-aging claims—not unverified claims about people living to extreme ages.

7 simple answers
peptides
No strong human evidence shows that BPC-157 heals tendon or ligament injuries. Most support is animal, cell or mechanism-based, and internet recovery claims should not be treated as proven clinical benefit.
peptides
TB-500 injury-recovery claims are not supported by strong human clinical evidence. The claim often relies on extrapolation from thymosin beta-4 biology and should be treated as unproven.
Longevity drugs
Rapamycin has unusually strong aging-biology interest, but it is not proven to slow human aging or extend lifespan in healthy adults.
Longevity drugs
Metformin is an important diabetes drug and longevity candidate, but it is not proven to extend lifespan in healthy non-diabetic adults.
NAD & supplements
NMN may affect NAD-related biomarkers in some studies, but that does not prove it slows human aging. The stronger claim needs clinical outcomes, not only a molecule-level signal.
NAD & supplements
There is no simple evidence-based winner between NR and NMN for longevity. Comparisons depend on dose form, endpoints, product quality and whether the outcome is a biomarker or a health result.
NAD & supplements
NAD IV anti-aging claims are not supported by strong evidence. Infusion marketing often uses cellular language that does not prove meaningful aging outcomes.
