The hormone that runs your ambition
dropped 50% before you turned 40.

Nobody told you. Not your ob-gyn at your annual. Not the lab report that said "within normal range" without telling you that "normal range" includes post-menopausal women. Not the FDA, which approved testosterone for 12 million men in 2000 and then spent the next 22 years explicitly refusing to approve it for women.

This isn't a story about libido. That's the reductive shorthand that kept the conversation small for two decades. This is a story about dopamine, motivation, executive function, bone density, muscle mass, cardiovascular protection, and the specific way your brain lights up when you care about something. Testosterone is the hormone that makes effort feel worth it. When it drops, effort still happens — you just stop feeling it.

I'm not a doctor. I'm a woman who founded a company at 35, ran orphanages in three countries, and spent my 50s wondering why the drive that defined me felt like it had moved to another zip code. The answer was partly in a lab panel nobody had ordered correctly. I want you to have the information I had to find myself.

// About this series

Six pieces.
The ones that should have been written 20 years ago.

The Testosterone Files is an investigative newsletter series on SmartStrongAlive — six essays that start with the FDA scandal and end with a practical guide to actually getting prescribed. In between: the brain science, the methodology failures that killed the research, the lab work that's been misread on your behalf, and an honest account of the side effects nobody prepares you for.

Each essay is sourced, cited, and written plainly enough that you can bring it to your doctor. These are not hopeful anecdotes. They are the peer-reviewed literature, translated for a woman with better things to do than read clinical trial PDFs at midnight.

The series is free to read. Subscribe to SmartStrongAlive and they arrive in your inbox.

22
Years the FDA stonewalled female testosterone approval Intrinsa was rejected in 2004. Nothing has been approved since. Men got theirs in 2000.
50%
Drop in testosterone from age 20 to 40 This happens before perimenopause. Most women are already in deficit before hot flashes start.
0
FDA-approved testosterone formulations for women in the United States, as of this writing. Physicians prescribe off-label. Most don't prescribe at all.

The manifesto. Why this series exists, what it covers, and what the FDA would rather you not read. Wide-funnel entry — share this one.

01
Zero for women. Twelve for men.
The FDA scandal. Steven Nissen's testimony, the Intrinsa rejection, and 22 years without a single approved formulation for women — while 12 million men got theirs in 2000.
→
02
It's a brain hormone, not a libido hormone.
Dopamine, anhedonia, and the motivation science. Why "low sex drive" is the least interesting thing testosterone affects — and what it's actually doing in your prefrontal cortex.
→
03
Why the research got it wrong.
Wrong assay. Wrong endpoints. Studies that ran six weeks and declared defeat. A methodological failure so consistent it starts to look deliberate — and what the better research actually shows.
→
04
Why your labs are lying to you.
SHBG, the birth control connection, and what "within normal range" actually means when the reference range includes 80-year-old women. The exact labs to ask for — and how to read them.
→
05
The side effects nobody prepares you for.
Hair, voice, clitoromegaly — honest, not scary. What actually happens at therapeutic doses, what the risk window looks like, and why the conversation about side effects has been used as a reason not to prescribe rather than a reason to prescribe carefully.
→
06
How to actually get it.
Delivery options compared (cream vs. pellet vs. injection vs. troches). How to find a provider who won't look at you blankly. Exactly what to say in the appointment. This is the practical episode.

// Why I wrote this

What the six-week studies missed

The clinical trials that "proved" testosterone didn't work for women had a shared problem: they used the wrong test to measure the wrong thing over too short a period in women who weren't selected for the deficiency they were studying. It is the research equivalent of studying whether reading glasses help people who don't need them, concluding they don't, and announcing that reading glasses don't work.

"The history of women's health is, in part, the history of questions never asked — because the researchers funding the studies weren't sure women's answers would be commercially useful."

— Annette Thompson, SmartStrongAlive

The better research — longer studies, correct assays, women selected for documented deficiency — tells a different story. Improved mood. Sharper cognition. Restored motivation. Maintained lean mass. Maintained bone density. The kind of outcomes that make you ask why this isn't a standard part of hormone replacement, the way estrogen and progesterone are.

The answer to that question is the series. It is not comfortable reading. It is accurate reading. There is a difference.

Annette Thompson

// Founder · Menopause Advocate · SmartStrongAlive

Annette Thompson, 57, is the founder of adoption.com (1995) — built in the early days of the web, when "building a website" was not yet a job title. She has run orphanages in Ethiopia, Kenya, and Haiti. She adopted seven children internationally. She has spent the better part of three decades doing things that didn't have instruction manuals yet.

She is not a physician. She has read a very large amount of clinical literature, found most of it poorly translated for the women it concerns, and decided to do something about that. She splits her time between Boulder, Colorado and Ajijic, Mexico — where she watches women in their 50s and 60s being told, in Spanish, the same things women in their 50s and 60s are being told in English: that what they're feeling is normal, that their labs are fine, and that they should maybe try yoga.

SmartStrongAlive is where she writes what she wishes someone had written for her ten years ago.
