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).
Anyone wanting to understand their personal food/exercise/sleep response to glucose, or working on insulin sensitivity.
You're prone to obsessing over normal variation, or you already have well-managed metabolic health and don't need data.
