What question the book answers
If your lab results came back normal and something still feels wrong, what does "normal" actually tell you, and what does it leave out? The book explains how reference ranges are built, why a result can sit inside a range and still be worth a conversation, and how to ask better questions of the people interpreting it.
What it deliberately does not promise
It does not diagnose, recommend treatment, or interpret your personal results. Dr. Michael Peters is a retired physician and does not practice medicine. The book teaches you to prepare for a conversation with a qualified clinician; it does not replace one.

Key terms and evidence tiers
Every major claim in the book carries a label: Tier A (strong human evidence), Tier B (some human evidence, with limits), Tier C (thin or early human evidence), or Preclinical (cells or animals only). The Two Questions run through every chapter: What tier is the evidence? Who profits if you say yes?
