Who should buy which
Anyone running peptides, optimizing hormones, on a longevity protocol, or just wanting twice-yearly comprehensive labs at a fixed price.
You already get comprehensive labs through your concierge clinic, or you only want the cheapest single-panel test (go InsideTracker).
Buyers who want test results paired with explicit "do X" recommendations rather than raw lab data they have to interpret.
You want maximum biomarker coverage at the lowest annual cost - Function Health wins on that math.
