Decision support
Questions to ask before you buy.
A short due-diligence list to apply before paying, booking, subscribing, or building a routine around any longevity tool, test, or program.
01
What exactly will this measure, track, or improve — and over what time horizon?
02
Is there medical or clinician oversight, and how qualified are the people behind it?
03
How should I interpret the data, and what does a meaningful change actually look like?
04
What will I do differently with the results? If the answer is unclear, the signal isn't useful yet.
05
Is the claim evidence-led or marketing-led? Where is the underlying research?
06
What is the true cost after the first purchase, test, or subscription — including renewals?
07
Does this replace medical advice? It should not. Where does professional care still belong?
08
How does this compare to simpler, lower-cost, or higher-evidence alternatives?
