Inside the playbook

What you'll actually get.

The framework

  • The five panels worth asking your doctor for, and the three most doctors never order unless you ask by name
  • How to read a “normal” range and tell when normal isn't the same as optimal
  • The difference between a thyroid panel that looks complete and one that's actually complete
  • What's worth a second opinion versus what to leave alone for now

The panel to order

  • The exact panel list to hand your doctor, test names included, so nothing gets left off the requisition
  • The $89 direct-to-consumer panel that covers what most annual physicals skip
  • Three AI prompts that turn a PDF of lab results into a plain-English summary in under two minutes
  • The one marker insurance almost never covers that's worth paying out of pocket for

Why I wrote this

I paid $400 to be told my labs were fine.

It was a functional medicine consult, spring of 2024. The intake was thorough, the labs were extensive, and the verdict was that everything was “in range.” It was, technically. But in range and optimal are not the same sentence, and nobody in that office was going to explain the gap for free. I went home and taught myself to read my own labs, panel by panel, the same way I'd research anything else — primary sources, AI to compare protocols, and enough repetition to stop needing the appointment. This playbook is that process, written down.

Honest answers

Things you're probably wondering.

Is this medical advice?

No. None of it is. I'm an operator who reads studies and runs my own labs through the same process I teach here. If a marker is genuinely abnormal, this playbook gets you to that conversation with your doctor faster — it doesn't replace it.

How long until I see results?

About 15 minutes to reread your last set of labs the way this playbook teaches. Most readers say the real payoff is retroactive — you'll want to pull results from a year ago and look again.

Will I have to order expensive tests?

No. Most of what's here works with labs you already have or can request through your existing doctor. The one direct-to-consumer panel I recommend is optional and costs about $89.

Can I upgrade to a bigger playbook later?

Yes. At checkout you can add the AI Wellness Audit ($79) or the full Library Bundle ($179) in one click. After purchase, you can buy additional playbooks at full price on the Library page anytime.

What's the refund policy?

There is none. All sales final. That's why Chapter 1 is free — so you can sample the method before you spend a dollar. If the free chapter doesn't sell you, the full playbook won't either.

Who is this not for?

Women who want a doctor to just tell them the answer. Women who don't want to look at their own bloodwork. Women who'd rather trust an influencer's supplement stack than a peer-reviewed range.

One $29 playbook. Fifteen minutes. Then you can read your own labs.
