One-to-one · planned
A focused longevity consultation
$97 USD per session. A clear conversation about your goals, your questions and what may be worth discussing with your own clinician. Online booking details are being prepared.
Testing · guides live
Understand what your numbers mean
Explore at-home sample kits, biological-age estimates and wearable recovery trends — and learn what each can, and cannot, tell you.
Peptide lessons · in development
Learn peptide science step by step
Short lessons are being planned around biology, mechanisms, human evidence, uncertainty and safety — so you can ask better questions before making decisions.
The foundations still matter
Small habits. Stronger foundations.
Our promise to readers
Curiosity, with the hype taken out.
Evidence with context
We distinguish human research from early, animal or theoretical evidence, and link readers to the sources.
Honest limits
A test is not a plan. A promising mechanism is not proof of benefit. We say what remains uncertain.
A useful next step
Every guide is written to help you make a thoughtful next move or have a better conversation with your clinician.
Free weekly longevity notes
One practical idea, the research behind it and a question to take forward. Once a week, no hype.
