A clear read on your health, built from your own biology.
Performance, measured.
Two minutes, and a doctor-led picture of where you actually stand.
Performance medicine · Medicine 3.0
What if your health wasn’t based on guesswork?
Performance medicine replaces assumption with measurement — a precise, personalised picture of how your body is performing, and how to make it better.
The journey
Five steps. One continuous relationship.
A guided, premium experience — measured at every stage.
- 01
Meet
An introduction appointment to understand your goals.
- 02
Discover
Advanced diagnostics map your whole system.
- 03
Interpret
Your data, read in context by clinicians.
- 04
Optimise
A personalised protocol you can actually live.
- 05
Retest
We re-measure, refine and compound progress.
Advanced Diagnostics
See what was always invisible.
A multi-system baseline — from deep pathology, DNA, fitness to biological age — captured as one picture, then tracked over time.
100+ markers
Blood Biomarkers
Cardiometabolic, hormonal and inflammatory markers — the signals that move years before symptoms.
Deep sequencing
Gut Microbiome
The bacterial ecosystem behind digestion, immunity and metabolism — mapped before anything else is built.
DEXA
Body Composition
Precise lean muscle, fat distribution and bone density — the picture a scale can never show.
Cardiorespiratory fitness
VO₂ Max
One of the strongest predictors of longevity — measured, then trained, then re-measured.
HRV · sleep architecture
Sleep & Recovery
The systems that restore you — tracked continuously, so training compounds instead of erodes.
Epigenetics · 11 organ systems
Biological Age
Your age is fixed; your biology is measurable — eleven systems, each ageing at its own rate.
Plus genomic testing, epigenetic age, microbiome analysis and cardiovascular assessment — with continuous data from wearables such as Oura and CGM.
The Unified Dashboard
Every signal, one picture.
Oura, WHOOP, Apple Health — your dynamic data in full view and monitored by us.
The PK27 Method
Test → Implement → Retest
Understanding becomes change through a continuous loop — never a one-off diagnosis.
01
Test
Establish the baseline.
Comprehensive, advanced diagnostics build a precise, multi-system picture of how your body is performing today — the objective ground truth every decision is built on.
Programs
Two ways to begin.
Are you coming to us about something specific — or do you want the full picture of where your health is at?
Whichever door you choose, the journey is the same — Insight, Educate, Empower.

About PK27
The essentials.
PK27 (Peak Health 27) is a precision medicine and performance optimisation practice in East Melbourne. We use advanced diagnostics and continuous data to help individuals and organisations measure and improve long-term health and performance — an approach we call Medicine 3.0.
Performance medicine optimises whole-system human performance — physical capacity, cognition, recovery and resilience — using objective, personalised data rather than population averages.
Longevity medicine is the proactive practice of extending healthspan — the years you live in good function — not just lifespan, by measuring and addressing the drivers of ageing early.
A GP is essential for reactive and acute care. PK27 is proactive and continuous: we build a personalised, multi-system baseline and track how it changes over time, so we can act early rather than react late.
PK27 is in East Melbourne — Level 7, 166 Gipps Street, VIC 3002. By appointment.
Begin
Your highest potential,
measured.
It begins with an introduction appointment — a conversation about your goals, and a clear path forward.
