Two newsletters.
One mission.
One is for serious readers. The other is for builders who know health care is harder than a deck.
The Longevity Letter
Subscribe and get the Supplement Stack: the short list of supplements that earn their place after my evidence, safety, and follow-through test. Then stay for the weekly note: studies, protocols, and claims I would not buy at face value.
Free. Every Friday. Unsubscribe anytime.
The CareCore Stack
A note for founders, innovators, and clinicians building health products with actual medical consequences: clinical workflows, regulation, unit economics, and where glossy health products fall apart.
Free. Weekly. Unsubscribe anytime.
Here for clinical care, not just the reading list?
The newsletter is the lightest way to follow the work. If you need a physician to interpret labs, risk, symptoms, or medications, start with the practice path.
What you’ll get
The Longevity Letter
Studies with consequences
Not every paper deserves a protocol. I write about the ones that might change care, and the ones to leave alone.
Protocols with stop rules
Supplements, training, labs, and medications need a reason to start and a reason to stop.
Clinical notes
What real patients ask, where standard advice gets thin, and how I think through tradeoffs.
The CareCore Stack
Care models
How longevity services are staffed, priced, documented, and kept medically honest.
Regulatory drag
The boring parts that decide whether a health product can survive contact with patients.
Builder's notes
What I am learning while building CareCore, including the parts that do not fit a launch post.

Builder notes are next
Subscribe above if you want the working notes on clinical product, operations, and care infrastructure, not the launch-post version.
