Longevity medicine · London
Know your numbers. Then change them.
One assessment day, run by doctors. Bloods, scans and VO2 max, then an hour with your physician and a plan for the year.
4 physicians · 2,400 assessments since 2019 · results in 10 days
The assessment, measured
One day. Five steps. Every number explained.
You arrive fasted at half past eight and leave by three. Ten days later you sit down with your doctor and read the results together.
What you take home
Your results, written for you, not for a lab.
A page from a Morrow report. Every marker with its optimal range, where you sit in it, and a line from your doctor.
