Where Data Becomes Direction.
Gold-standard health and performance assessments — designed for those who demand precision, longevity, and peak performance at every stage of life.
Blue Zones Longevity.
Gold Standard Science.
The name Blue and Gold Labs is not arbitrary. Every word reflects our purpose. Blue is our commitment to healthspan — drawing inspiration from the world's Blue Zones, where communities live with exceptional vitality well into their nineties and beyond.
Gold is our commitment to rigor. We use only gold-standard measurements — the same protocols trusted by elite athletic programs and leading longevity researchers — to give you objective, reproducible data that tracks your progress over time.
Together, they define who we are: a precision health practice where science serves life.
Cardiovascular Health
Advanced blood markers reveal what standard panels miss — including ApoB, Lp(a), and precise metabolic zone thresholds that define your true cardiovascular fitness.
Body Composition
Clinical-grade DEXA scanning measures fat, lean mass, and bone mineral density with millimeter precision — performed fasting for the most accurate baseline possible.
Performance Optimization
ACSM-validated fitness testing and VO₂ Max assessment provide the objective data every serious training strategy demands — from weekend warriors to competitive athletes.
Recovery & Sleep
Multi-night at-home sleep studies capture the quality and architecture of rest — because recovery is where adaptation happens and longevity is quietly won or lost.
Precision Health for
Three Distinct Journeys
Every client arrives with different goals. Our assessments speak to all of them.
Health-Conscious Individuals
You invest in your health today so it pays dividends for decades. Quarterly tracking gives you the longitudinal data to know what's working, what's changing, and what to adjust — before problems arise.
Athletes & Weekend Warriors
Training harder isn't always training smarter. Objective VO₂ Max data, zone thresholds, and body composition tracking let you refine your approach with the same precision a professional program demands.
Reclaiming Your Metabolic Potential
Your metabolism is not fixed — it's a system that responds to the right information and the right interventions. Whether you're optimizing nutrition, exploring GLP-1 therapies, or building toward a leaner, stronger body, our assessments give you and your care team the precise metabolic data to accelerate results and sustain them for life.
Six Pillars.
One Complete Picture.
Each quarterly session integrates six gold-standard assessment modules into a single, coherent health narrative.
More Than a Full Day
Invested in You Each Year
Four quarterly sessions. Ten hours of gold-standard assessment annually. More clinically meaningful data than most people collect in a lifetime — all focused entirely on you.
Fasting Blood Draw at LabCorp
Complete your advanced blood panel at any LabCorp location near you — on your own schedule, before your in-clinic assessment day. Lab fees are fully included in your membership. Results are shared directly with Blue and Gold Labs for integration into your consultation.
DEXA Body Composition and Bone Mineral Density
Begin fasting with your clinical DEXA scan — the most accurate body composition measurement available. Fasting state ensures the highest precision for fat mass, lean mass, and bone mineral density readings.
Resting Metabolic Rate
Immediately following the DEXA scan — while you remain still on the scanner bed — a canopy indirect calorimetry measurement captures your true resting metabolic rate. The supine, fasted state is ideal for RMR accuracy, and the seamless transition eliminates any activity that could elevate your baseline. This is part of your Metabolic & VO₂ Max pillar.
ACSM Fitness Battery
Standardized fitness evaluation covering muscular strength and endurance, flexibility, cardiovascular baselines, and body measurements.
Metabolic & VO₂ Max Testing
Graded exercise protocol with breath-by-breath gas analysis to determine your precise metabolic zones, ventilatory thresholds, and aerobic ceiling. Performed last as the most physically demanding assessment.
Glucose Response — CGM Setup & Protocol
Receive your continuous glucose monitor (CGM) and walk through the self-discovery protocol with your practitioner. Learn how to interpret your real-time glucose data across food, exercise, stress, and sleep — so the 10–14 days of monitoring that follow become a true learning experience, not just raw data.
Sleep Study Device & Wrap-Up
Collect your at-home sleep study device with setup instructions for your 5–7 night home recording. You're done — and your follow-up consultation is scheduled.
Integrated Results Consultation
Once your blood results, CGM data, and sleep study are complete, your practitioner meets with you in-person or via teleconference to synthesize all six data streams into a unified, actionable health plan — personalized for the quarter ahead.
Invest Once.
Track Everything.
Choose a single assessment or commit to the full year — four quarterly benchmarks that build a longitudinal picture of your health no single test can provide.
"At Blue and Gold Labs, data becomes direction — and direction becomes results."
Medical & Scientific
Leadership
Blue & Gold Labs brings together technical precision and clinical depth. Every assessment is led through a structured testing process by Dr. Davis, with Dr. Hood available for consultation whenever a client’s findings call for specialized cardiovascular expertise.
Pepe Davis, PhD
Pepe Davis, PhD, is the Chief Executive Officer of Blue & Gold Labs and personally guides every client through the assessment process. A physicist, engineer, and medical device executive with more than 25 years of experience, he oversees equipment selection, protocol design, test execution, and the integration of results into a precise and coherent picture of health.
Dr. Davis holds a BS in Engineering Physics, magna cum laude, from the University of California, Berkeley, and a PhD from the University of California, Los Angeles, in non‑linear optics and plasma physics. Over his career, including more than 15 years with Carl Zeiss Meditec, he has held senior roles in research, development, quality, regulatory, and clinical affairs at both high‑growth startups and multinational medical device companies. His work spans cardiovascular imaging, ophthalmic imaging, neurology‑related biomarker projects, metabolic health technologies including non‑invasive continuous glucose monitoring, and advanced nuclear imaging systems.
At Blue & Gold Labs, Dr. Davis co‑developed and qualified the biometrics program and remains directly involved in every client journey. His current focus is on personal biometrics that correlate with healthspan—the years lived in genuine vitality—and are truly actionable through lifestyle choices, particularly diet and exercise.
James Hood, MD
James Hood, MD, is Chief Medical Officer and Medical Director of Blue & Gold Labs and serves as the lab’s senior clinical authority. He is a board‑certified cardiothoracic surgeon with more than 25 years of experience treating complex cardiovascular and thoracic disease in the San Francisco Bay Area.
Dr. Hood began his training in Chemical Engineering (BS, cum laude, Auburn University), then earned his MD from the University of Alabama School of Medicine, completed a general surgery residency at LSU–Shreveport, and trained in cardiothoracic surgery at Thomas Jefferson University in Philadelphia. From 2000 through 2022 he served as a cardiothoracic surgeon at Kaiser Permanente San Francisco, recognized as a San Francisco Magazine / Castle Connolly “Top Doctor” for eight consecutive years.
His research includes numerous peer‑reviewed publications in pulmonary vascular physiology, cardiovascular pharmacology, and complex surgical care. At Blue & Gold Labs, he co‑designed the advanced cardiometabolic and performance testing protocols and is available for consultation when a client’s results raise complex cardiovascular questions or require higher‑level clinical interpretation.
