Why you still don’t know
Feeling fine, doing “the right things”, and still no idea if any of it works? It’s not you. Your passport counts years. A checkup reads a snapshot. Neither tells you how fast your body is aging. DunedinPACE does: biological days aged per calendar day. Measure it, change one thing, measure again. That’s the whole system.

Not a classic one. It’s an epigenetic test that uses blood as the sample. A home blood test can only report as many markers as its small vial allows, which is why broad panels usually mean a clinic visit and several tubes. An epigenetic test reads the layer on top of your DNA and estimates a wide range of markers from it, some that a classic blood test can’t measure at all: VO₂ max, lung function (FEV1), gait speed, grip strength and telomere length.
How fast you age is being decided now, not at 80. Feeling fine is exactly when the number is most useful.
Then you’re in good company: every person who has tested with us so far has had at least one result out of range. That’s normal, and it’s what the test is for: to show you where to focus, so you can build a plan around it. Most of what we measure responds to what you change, at home or with a professional, and your plan starts there.
No prescription, no appointment, no vein. Every kit includes a Tasso device on your upper arm: press the button, a tiny lancet takes a few drops, practically painless, about ten minutes.
