Hey Joseph - I certainly can empathize with the stance that what can biological test provide.
Although Matt Kaeberlein has his doubts on epigenetic testing. I am focusing on two areas of testing that seem to be pretty good and not a shotgun approach to here is your biological age. I focus on inflammation which can be understood from your glycan assessment. The number one authority on this is Gordon Lauc. So this test shows me where I am at with inflammation. Rapamycin should reduce your inflammation well below your average normal levels for your age. Was used as a baseline and post test for PEARL trial. That is a pretty high bar to get used. Been Glycan testing and monitoring for 3.5 years.
The other area that can show aging is Methylation DNA. Respected anti-aging specialist Dr. Yelena Budoskaya who work with tick virus testing and more shows she is no charlatan in the science field. She does one thing and well once again. For me using two test consistently I think keeps me on track for all my anti-aging work. Testing as I try new things. You might think these companies will tell you whatever you want to hear. Not so, both GlycanAge and TruMe say my biological age results are atypical - I am a fraction of a fraction for my age based on my many tests which are consistent (others like me simply do not exist. This directly from Dr. Budovskaya and Dr. Lauc’s team) . It has to be the rapamycin.
If you want more on why I pick these tests - mainly due to the caliber of the leadership and these company’s respect in the aging field.
Glycobiology simplified: diverse roles of glycan recognition in inflammation
Understanding glycans and chronic inflammation is the main feature of many long-term inflammatory diseases such as autoimmune diseases, metabolic disorders, and cancer.

The company GlycanAge under the direction of Dr. Gordan Lauc has developed lab work looking at blood that measures your glycan structures and can accurately identify your level of inflammation.

I am newly enrolled in the PEARL study (PEARL Trial to Prolong Life With Longevity Products | AgelessRx 1, Participatory Evaluation (of) Aging (With) Rapamycin (for) Longevity Study - Full Text View - ClinicalTrials.gov 1); I was admitted shortly before they stopped enrolling new participants. I talked with “Dr. Z” (Sajad Zalzala) on Zoom, and also in person at RAADFest in October. I’ve completed the informed consent, initial blood tests, DXA scan, GlycanAge and Thorne Microbiome tests, and as of this date I’ve taken two weekly doses and completed two weekly reports (blood pressure and some health questions).
I haven’t yet received results from the GlycanAge test. I have had a series of epigenetic age tests, because I previously participated as a subject in the TRIIM-X clinical trial (http://interveneimmune.com/, Thymus Regeneration, Immunorestoration, and Insulin Mitigation Extension Trial - Full Text View - ClinicalTrials.gov). I have learned to view the epigenetic age measures as relative measures, and not to take too seriously the reported “age” as a comparison to chronological age. (I have seen a 28-year range in epigenetic “age” measures computed from a single methylation dataset, using the same blood sample – with PhenoAge the lowest and GrimAge the highest.) So I’d say you have a signal to reduce your Rapamycin dose, but I wouldn’t interpret this as a “real” 15 chronological year change.
The Company TruMe developed by Stanford Anti-aging specialist Dr. Yelena Budovskaya.
Interview of Dr. Budovskaya with respected anti-aging Dr. Robert Lufkin MD – rapamycin expert. I was one of the off label users who’s blood was tested by Dr. Lufkin. After my blood work was done I received a voucher for Amazon – nice. Supplement money.
