Why we quote Miller

The ITP is the only program that tests candidate longevity drugs in genetically heterogeneous mice at three independent sites simultaneously. It is the reason we know rapamycin works late in life and that fisetin does not extend lifespan.

Richard A. Miller, MD, PhD is one of the researchers quoted here; the others quoted alongside Richard are listed with the same disclosures.

Where they stand, and who pays

Publicly funded, sells nothing, and has published null results on compounds the supplement market was already selling.

Stating this next to the quote rather than at the bottom of a disclosures page is the whole point. A concession made against a commercial interest is stronger evidence than a neutral summary; a claim made in line with one is weaker. You cannot weigh either without knowing which you are reading.

Every line below is transcribed from a public recording and linked back to it. Nothing here is paraphrased, and Miller has no relationship with this site.

Everything we quote them saying

All 2 lines, verbatim, in the order they appear in the site's citation index. Each one links to the recording and to the page it is used on.

It was stunning that a drug could start as late as that and still have a full lifespan benefit.

We thought we were testing the notion that removing senescent cells would be good for you, and it turned out we were testing the notion that fisetin removes senescent cells.
