Most people don’t lose their health suddenly. They lose it slowly, in ways that can be measured years in advance.

Healthspan, not hype.

Longevity has become a buzzword, and an industry has grown up around it: supplements, unproven drugs, and biological-age tests that no one has shown change how long or how well you live. GC Prime is built on a different principle. We focus on the things the evidence shows keep people healthy for longer: early detection of heart disease, cancer and dementia risk, cardiorespiratory fitness, muscle strength and metabolic health. We measure them properly, act on them, and measure again.
“Built by scientists, not influencers.”
We don’t sell anti-ageing supplements. We don’t promise to reverse your biological age. We don’t recommend anything we can’t support with evidence.

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.

Your year in GC Prime

Discover.

Complete baseline screening: a CT heart scan and heart imaging, advanced blood and genetic testing, cancer screening and full performance testing. Review every result with Calum or Rob and Dr Hula, then receive your personal Prime Plan.

Rebuild.

Start your nutrition and training programmes, with your nutritionist every two weeks and medical treatment where clinically appropriate. Retest at the end of the quarter.

Strengthen.

Progress the plan based on your numbers. Quarterly retest, results review and medical review.

Review.

Full end-of-year retest and your annual written health report: what changed, what it means, and your roadmap for the year ahead.

What we measure.

Every test is chosen because it predicts disease or changes what we do. Nothing is included for show.

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.

Frequently Asked Questions

Click below to find answers to our most common questions.
Is GC Prime a longevity clinic?
We prefer the word healthspan: the years you spend in good health. Longevity science studies how to extend human life itself, and no one can yet promise that. What the evidence does support is protecting and improving the years you have, and that is what GC Prime is built to do.
No. Epigenetic “biological age” tests can predict risk across large populations, but there is no evidence that lowering your score helps you live longer or better, and results can vary between repeat tests. We measure things we can act on: fitness, strength, body composition, blood markers and heart health.
Where it is clinically appropriate, Dr Hula can prescribe and manage treatment, including hormone and weight management. Any medication is a medical decision based on your results, never an add-on.
Dr Hula reviews it with you and, where needed, we arrange a fast-track referral to the right specialist, private or NHS.
No. GC Prime works alongside your GP and NHS screening programmes, and we encourage you to keep them up to date.
Yes. International members travel to London for their screening: blood tests and performance testing at our clinic at 104 Harley Street, and heart imaging at The National Heart Clinic. The rest of the programme runs remotely with your team.
Membership is by application. We discuss fees during your confidential call.
No screening test can detect every disease, and a normal result does not rule one out. Screening results can sometimes need further tests to confirm. GC Prime does not replace your GP or NHS screening programmes. If you have symptoms, please see your GP.
