Exclusive access to GrimAge in Australia - the gold standard biological age test developed by UCLA Horvath Lab. Analyzes DNA methylation markers across 8 protein markers (PAI-1, Cystatin C, Leptin, TIMP1, ADM, B2M, GDF15) plus smoking history. Measures cellular aging to predict age-related disease and mortality risk. Non-invasive sample collection with detailed results review.

Biological age testing estimates how old your body is at a cellular level — which may differ significantly from your chronological age. These tests use various biomarkers and algorithms to calculate your biological age, including metabolic markers, inflammatory markers, organ function tests, and in some cases epigenetic (DNA methylation) analysis. A biological age younger than your chronological age suggests your body is aging well, while an older biological age may indicate accelerated aging from lifestyle factors, chronic stress, or disease. This emerging field of longevity medicine provides a tangible score to track the impact of diet, exercise, sleep, and supplementation interventions over time.

Who Is This For?

Health-conscious individuals interested in quantifying their rate of aging. Longevity enthusiasts following structured optimization protocols and biohacking regimens. Anyone wanting a single metric to track the overall impact of lifestyle changes. People in their 40s–60s who want to understand if their health habits are slowing biological aging.

What's Included

Panel of biomarkers used to calculate biological age
Biological age score and comparison to chronological age
Specific markers vary by provider and methodology

Preparation Required

Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
