One that is not on the list that I highly recommend is Insidetracker's InnerAge test. It's a blood test using a group of biomarkers known to influence longevity. David Sinclair is on the board and takes this test. It's $99 for 5 different blood tests, including tests for glucose levels, testosterone for men - DHEAS levels for women, hs-CRP for inflammation levels (and a good measure of your possible senescent cell levels), Vitamin D levels, and ALT (liver function). I used a coupon code INSIDETRACKER20 for 20 percent off and got the test for $79. I'm not sure where else you can get such a deal for this kind of valuable blood test.
“I was impressed. I didn’t expect to gain an extra decade. And I certainly didn’t expect it to happen over a matter of months. So when I got my InnerAge results just a few days ago, I was jumping for joy.” - DAVID SINCLAIR
