Bellwether Membership
Membership covers two full panels a year: one to set your baseline across 118 labs, and a second six months later to see what moved.
- 118 labs tested every year
- A protocol that gets revised as your results move
- Your biological age, tracked across a lifetime
Pricing may vary for members in New York and New Jersey **
What is included exactly?
Two draws a year covering 118 biomarkers, a written interpretation from a clinician, and a protocol you can act on. Add-on panels are priced separately.
Where do I go for testing?
Any of the 2,140 partner draw sites across the country, or a mobile phlebotomist at home in most metros. You pick the slot when you join.
How is Bellwether different?
Routine panels look at roughly 20 markers once a year. We look at 118 twice a year, and we read them against your own history rather than a population average.
Do I need insurance?
No. Membership is a flat annual fee and does not touch your insurance. HSA and FSA cards are accepted at checkout.
Does this replace my primary care provider?
It does not. Bellwether sits alongside primary care — we share every result in a format your physician can read and act on.
Why can't I order these tests through my doctor?
Some you can. Most of the longevity markers fall outside standard reimbursement, so they are rarely ordered unless something has already gone wrong.

What we believe
We think that if you improve your health, you improve nearly every other part of your life.
Mainstream medicine has not made that easy for most of us.
It is built for averages, it reacts late, and it rarely sees the whole picture.
We built Bellwether to change that.
