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 frequent, low-friction biomarker tracking without lab visits or needles, especially anyone testing quarterly to watch trends rather than once a year. HSA/FSA users get a meaningful pre-tax discount.
You want the single broadest one-time panel (Function 160+ or Mito 100+ markers with clinician review), or you need an active prescribing relationship for hormones or GLP-1s - this is testing and insight only.
