Increase Your Lifespan and Your Healthspan.

Bio-Span X is the first evidence-based precision longevity programme built around three core pillars of: disease-risk elimination, metabolic transformation and measurable biological age reversal. Most "longevity" companies sell supplements, unproven interventions, and fragmented testing with no outcomes. At GC Biosciences, we do the opposite. We deliver a medical, data-driven, precision longevity system for driven individuals who demand results.

DISEASE RISK
ELIMINATION

Identify & eliminate risk factors for the Big 3 major killers: cancer, CVD, dementia.

METABOLIC
TRANSFORMATION

Rebuild your metabolic machinery, cardiovascular engine and body composition.

REVERSE BIOLOGICAL
AGEING

Track & reverse key biomarkers of ageing, cardiometabolic health & body composition.

The 3 Phases Of Healthspan Optimisation.

The Bio-Span X programme focuses on three progressive phases designed to help you predict and prevent disease, build excellent metabolic health & reverse biological ageing.

Optimise Your Biology

Identify & Eliminate hidden risks
for cancer, cardiovascular disease,
dementia, metabolic disease &
accelerated ageing

Rebuild Your Foundation

build the foundation with
evidence-based, personalised
optimisation of your exercise,
nutrition, vO2 max, metabolic
health & body fat %

Extend Your Healthspan

once you've rebuilt your
foundation, we'll explore select
precision longevity interventions
to help reverse biological ageing

Bio-Span X is an elite annual metabolic health and longevity programme delivered in three consecutive phases. Full details of each stage, including timings, programme components and tests are outlined below. The initial programme lasts for 12-months, depending on adherence and progress. In order to deliver the highest standard of care and results, successful completion of each phase and target biomarkers and body-composition targets is required before you can progress to the next phase. Following the successful completion of the initial 12-month programme, continuation options are available upon request.

1.

Protect Your Biology

Phase 1 Duration: 4 Weeks.

The most comprehensive medical screening protocol in UK private healthcare. Identify hidden risks for cancer, cardiovascular disease, dementia, metabolic disease and accelerated ageing. Translation: “don’t die.”

  • Cancer Screening: Datar Cancer Genetics Test (ultra-high sensitivity early cancer detection).
  • Cardiovascular Health: Stress ECG, Carotid Artery Doppler Scan, Advanced Lipid Panel + Lipoprotein Analysis, hsCRP & Inflammatory Markers.
  • Genetic Risk Profiling: APOE Genotype (dementia risk), CVD Genetic Profile, Additional Longevity & Metabolic variants.
  • Performance & Physiology: DEXA Body Scan (body composition & visceral fat), VO2 Max Test (cardiovascular fitness age), RMR (resting metabolic rate).
  • Biological Ageing: Epigenetic Methylation Test (baseline biological age).
  • Risk Discovery Session: Complete Health-Risk Map, Identification of Red Flags, Interpretation of all Major Biomarkers, Genetic Disease Predispositions, Cardio-metabolic & Biological age baseline.
  • Action Prescription Session: Personalised Nutrition Programme, Hormonal Optimisation Strategy, Supplement Protocol, Exercise Prescription (based on VO2 Max), Early Medical Recommendations (if indicated).
  • Regular Consultations with your dedicated health team (nutritionist, health coach, medical doctor, lead consultant).

2.

Optimise Your Foundation

Phase 2 Duration: 12 Weeks*.

The core of the Bio-Span X programme, phase 2 focuses on personalised interventions to help you optimise your: exercise, nutrition, VO2 Max, metabolic health and body fat %. The sciences is decisive – these are the dominant drivers of longevity. Phase 2 builds the foundation for advanced longevity interventions in Phase 3.

  • Graduation Benchmarks: 80% adherence to Nutrition & Exercise Programmes, along with demonstrated improvements in: Body Composition (DEXA scan), Metabolic Markers (HbA1c & lipids), Cardiovascular Performance required to progress to Phase 3.

  • Personalised Programmes: Data-driven Personalised Nutrition & Exercise Programmes Updated every 4 weeks, Personalised Supplement Protocols.

  • Monthly Screening / Tests: M360 advanced blood panel, DEXA Scan, VO2 Max every 4 weeks.

  • Expert Guidance & Support: Regular consultations with your Nutritionist (every 2 weeks), Health Coach (every 4 weeks), Medical Doctor Consultation (at the end of each phase).

  • Hormone Optimisation (TRT / HRT): Hormone Therapy review every 4 weeks if indicated and prescribed.
  • Peptide Therapy: Possibility of introducing specific peptides to control appetite, weight, metabolic regulation (in clinically indicated).

  • Action Prescription Session: Personalised Nutrition Programme, Hormonal Optimisation Strategy, Supplement Protocol, Exercise Prescription (based on VO2 Max), Early Medical Recommendations (if indicated).

  • Concierge Level Support: Unlimited support from our concierge client team, and office hours support from your dedicated health consultant.

3.

Extend Your Healthspan

Building on a solid foundation of improved metabolic health, Phase 3 runs for the remainder of the 12-month programme (typically lasting 8 months) and focuses on precision longevity interventions designed to help you maintain excellent metabolic health and reverse biological ageing, using evidence-based interventions backed by rigorous science (not influencer-driven marketing). Successful graduation of Phase 2 is required before commencing Phase 3.

  • Repeat Testing: M360 advanced blood panel, Advanced Hormone panels, DEXA Scans, VO2 Max, RMR, Epigenetic Biological Age re-test, (excludes Cancer % CVD screening).

  • Precision Longevity Interventions: Personalised therapeutic protocols and interventions based on your unique needs and data including: NAD+ protocols, Metformin (where indicated), GLP-1/Dual Agonists (part of long-term strategy), Rapalogs (research-backed frameworks), Fasting Scripts & Circadian Optimisation, Mitochondrial Function Protocols, Advanced Personalised Supplementation Strategies.

  • Action Prescription Session: Personalised Nutrition Programme, Hormonal Optimisation Strategy, Supplement Protocol, Exercise Prescription (based on VO2 Max), Early Medical Recommendations (if indicated).

  • Concierge Level Support: Unlimited support from our concierge client team, and office hours support from your dedicated health consultant.

Calum D. Gore

Co-founder, BSc, MSc, PhD Postgraduate Researcher

Calum Gore is a cardiovascular scientist and the founder of GC Biosciences, a leading UK service dedicated to high-performance health optimisation, metabolic transformation, and evidence-based disease-prevention strategies. Since launching the company in 2013, Calum has worked with thousands of clients including executives, athletes, and individuals with high health ambitions helping them understand their biology and improve long-term health outcomes through data-driven lifestyle interventions.
 
Calum holds a BSc in Health Sciences, specialising in human nutrition and immunology, and an MSc in Chronic Disease and Immunity, where he focused on the biological mechanisms underpinning disease dysfunction, inflammation, and long-term disease progression. He originally trained as a personal trainer and strength coach, using this background to fund his academic path and develop a deep understanding of applied human physiology, exercise prescription, and body composition change.
 
Today, Calum is a PhD post graduate researcher at University of Leicester in Cardiovascular Genetics, where his research investigates telomere length dynamics in vascular smooth muscle cells-a central mechanism in biological ageing, cardiovascular disease progression, and cellular resilience. This work directly informs GC Biosciences’ approach to disease prevention, metabolic optimisation, and biological age reversal.
 
Across his career, Calum has integrated laboratory science, cardiometabolic research, performance physiology, and real-world clinical data to build a model of health optimisation that is evidence-based, personalised, and outcomes-driven. His expertise bridges the gap between academia and practical intervention, allowing clients to understand their biology in a level of depth rarely available in private medicine.
 
Calum’s mission is simple:
to prevent disease before it starts, reverse biological ageing where possible, and give individuals the metabolic and cardiovascular foundation needed for lifelong performance and longevity.
 
This philosophy powers GC Biosciences’ new Precision Healthspan Programme – a scientifically rigorous, medically supervised system built to identify every major health risk, transform metabolic and cardiovascular function, and deliver measurable improvements in healthspan and biological age.
