The PhenoAge formula is public, peer-reviewed, and free. We didn't invent it and we're not hiding it — you can calculate this yourself from any standard blood panel, as many times as you like. We never store your data; you enter it yourself. If any company charges you for a biological-age number from standard bloodwork, you now know enough to walk away.
