The Protocol
Calibre's methodology is built on decades of performance and health research, integrated with traditional and Eastern European performance practices where the evidence supports them. This is not generic health advice. This is precision performance for people operating at the highest level.
The protocol works across five levers. Each is read from your data and sequenced against the others.
Where a recommendation moves beyond performance coaching (prescribed supplementation, clinical intervention), we don't improvise. We flag it and refer it to the right professional. That line is deliberate.
Sleep & Cognition
Sleep is active biological maintenance. We build protocols around sleep architecture, circadian optimisation, and cognitive maintenance. One week of five-hour nights reduces testosterone by 10–15% (Leproult & Van Cauter, 2011). Sleep deprivation impairs judgment while leaving routine tasks intact. This is why sleep-deprived executives often cannot detect their own decline.
Nutrition & Metabolic Health
Blood sugar stability is one of the largest levers on afternoon energy and decision quality. We design individualised nutrition protocols based on your metabolic profile, activity level, and biomarker data. Early metabolic problems rarely show on a standard GP panel, because the panel isn't looking for them.
Supplementation
Approached with restraint, not enthusiasm. Where supplementation is appropriate, it is evidence-based, screened against your health history and medications. Where it requires clinical oversight, it is referred, not freelanced. No generic stacks. No guesswork with your physiology.
Movement & Recovery
Exercise is a stress; recovery is where adaptation happens. We design movement protocols that build capacity without creating fragility. Each one-MET increase in cardiorespiratory fitness corresponds to roughly a 12% reduction in all-cause mortality (Myers et al., 2002). Moving from low to moderate fitness is associated with around a 50% reduction in mortality risk (Kokkinos et al., 2012).
Biomarker Interpretation
Standard medical reference ranges are designed to identify disease, not to optimise performance. A result within the normal range can still represent a meaningful performance deficit. Low-normal testosterone, early insulin resistance, and poor aerobic fitness all fall within "acceptable" while quietly degrading cognition, energy, and recovery. We read your bloodwork against performance-optimal ranges.
How It Works
This is a partnership. We bring the framework, the screening and the follow-up. You bring the execution.

Illustrative readout. Performance ranges vs. clinical normal ranges.
| Biomarker | Result | Clinical Normal | Performance Optimal | Status |
|---|---|---|---|---|
| Total Testosterone | 0 ng/dL | 300–1000 ng/dL | 500–800 ng/dL | Optimal |
| Fasting Glucose | 0 mg/dL | 70–100 mg/dL | 80–90 mg/dL | Monitor |
| VO₂ Max | 0 mL/kg/min | 35–50 mL/kg/min (avg) | 50+ mL/kg/min | Optimal |
| LDL Cholesterol | 0 mg/dL | <100 mg/dL (optimal) | 70–100 mg/dL | Optimal |
| Cortisol (8am) | 0 µg/dL | 10–20 µg/dL | 12–18 µg/dL | Monitor |
Values shown are illustrative. Ranges are performance targets, not clinical disease thresholds, and are under ongoing review.
Sample Protocol
A full protocol built on a synthetic client profile, to show the level of specificity you receive.
This document was generated for a constructed profile, not a real client. Every value, medication and recommendation in it is illustrative. It is here so you can see exactly how a protocol is structured, screened and cited before you commit.
Screened for contraindications and drug interactions as every client protocol is. No client data appears in this document.
Common Questions
What if I don't have biomarkers?
We arrange it. A first blood panel is part of onboarding, so you don't need existing results to start.
How long does the protocol take to show results?
Sleep quality and daytime energy typically shift first, within the opening weeks. Biomarker and metabolic changes take longer and are confirmed at retest.
Is this a diet plan?
No. A diet is something you stop. This is a nutrition system built around your data and your life, designed to hold.
Can I do this remotely?
Yes. Consultations and protocol work are remote. Bloodwork is arranged through UK laboratories; if you're based elsewhere, raise it on the qualifying call.
What if I need medical support?
We refer. Where something needs a doctor, a prescriber or a diagnosis, we connect you with the right professional rather than improvise.
How is this different from general health coaching?
We start with your data, not assumptions. Every recommendation is tied to your bloodwork, wearables, and biomarkers. We retest on a defined schedule and adjust. The protocol is a living system, not a document you read once.
What happens in the first month?
You receive your WHOOP, complete the structured intake, and have your first blood panel drawn. Your first protocol is written from that data, screened, and walked through with you on a call.
How is the protocol checked before I get it?
Every recommendation is screened against your medications, your health history and the interaction data we hold. Anything that crosses into clinical territory is referred rather than issued.
