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).
Longevity-focused buyers running serious anti-aging protocols who want validated pace-of-aging tracking, and biomarker-literate users adding epigenetic data to a broader monitoring stack.
You want actionable health recommendations (Function Health or InsideTracker beat it on that), you won't commit to longitudinal retests (single-point readings are noisy), or you're shopping for vanity rather than research-grade data.
