Healthspan, not hype.
“Built by scientists, not influencers.”
DETECT
Find heart disease, cancer and dementia risk years before symptoms, using a CT heart scan, advanced bloods and targeted genetic testing.
REBUILD
Raise the markers that predict a long, healthy life: fitness, strength, body composition and metabolic health, with a plan built around your results.
SUSTAIN
Retest every quarter, adjust as you go, and finish the year with a written roadmap for the decade ahead.

What we measure.

Your heart.
A CT coronary calcium scan, one of the strongest predictors of future heart attack in people without symptoms,6 plus a stress ECG, echocardiogram and carotid Doppler scan at The National Heart Clinic, all reviewed by consultant cardiologist Dr Francesco Lo Monaco. Advanced lipid and lipoprotein analysis, Lp(a) and inflammatory markers.

Cancer.
A multi-cancer blood screening test, alongside guidance on the NHS screening you should keep up to date.

Your brain.
APOE genotype, the strongest common genetic risk factor for Alzheimer’s disease, with a consultation to explain what your result does and doesn’t mean.5

Metabolism and hormones.
Our M360 advanced blood panel and hormone panel, repeated every quarter.

Body and performance.
DEXA scan (body composition, visceral fat and bone density), VO2 max, resting metabolic rate, grip strength and mobility, repeated every quarter.

Who GC Prime is for.
Founders, executives and senior professionals, typically aged 40 to 65, in the UK and internationally, who treat their health with the same seriousness as their work. People who want to know exactly where they stand, and a team that will act on it.
Discretion, as standard.
Our members include business leaders and elite athletes who value their privacy, so we don’t publish case studies or client names. What we can share is how we work: every test explained, every recommendation justified, and every result reviewed by people who know you.
Twelve places a year.
We keep GC Prime small so every member gets our full attention.
