Outliyr Releases Biological Age Testing Case Study Revealing 13.1-Year Variation Across Seven Products

(MENAFN- GlobeNewsWire - Nasdaq) Same-day comparison conducted by Outliyr founder Nick Urban shows major discrepancies between biological age results using epigenetic clocks, glycans, RNA multi-omics, and clinical biomarkers.

Austin, TX, Aug. 29, 2025 (GLOBE NEWSWIRE) -- Outliyr , a platform for high-performance Bio-Optimization, today released the results of an independent case study evaluating seven different biological age tests conducted on the same individual, on the same day. The analysis-led by Outliyr founder Nick Urban-revealed a striking 13.1-year spread between the highest and lowest biological age results. While the average biological age (30.4 years) matched the participant's chronological age, the study raised important questions about the consistency, reliability, and interpretation of current longevity diagnostics.

Key Highlights

• Same-day, same-person testing across seven biological age tests showed a variance.
• Technologies compared included epigenetic methylation, glycan profiles, RNA sequencing with multi-omics, and classical clinical biomarkers.
• Chronological age : 30.4 years.
• Range : ±13.1 years.
• Median biological age : 30 years.
• Average biological age : 30.4 years.
• Total testing cost (retail) : $3,143.99.
• The interactive dashboard (linked below) offers full transparency with test-by-test comparison. It also explores how lifestyle factors such as dry fasting influenced results.

Direct-to-consumer biological age tests have become increasingly popular, often marketed as quick insights into one's physiological age. Yet experts remain cautious. While the science is promising, the technology still has room to grow.

Nick Urban, founder of Outliyr, set out to test that gap. He conducted a controlled, same-day comparison using seven different biological age tests and cellular health tests. The retail cost would've totaled $3,143.99. The results clustered around his chronological age of 30.4 years but revealed a striking spread. This demonstrated some overlap but also significant discrepancies depending on methodology.

Urban also introduced a lifestyle perturbation, dry fasting , ending five days prior to testing in order to see whether the tests were reactive to short-term changes. Few existing reviews have examined this question.

The outcome was a highly transparent, interactive dashboard that allows readers to explore differences in test techniques, variance, and practical implications for longevity enthusiasts, clinicians, and the biohacking community.

The case study provides lessons for multiple audiences. For consumers, it shows the importance of understanding what different tests measure and their limitations. For longevity professionals, it offers a rare side-by-side breakdown to guide more informed recommendations. For self-quantifiers and biohackers, it provides transparency and interpretability.
