How I Use Science to Age in Reverse | Biomarkers, NAD+, Peptides & Longevity Strategy

What does “aging in reverse” actually mean — and how do you approach longevity without chasing trends? In this video, I share how I personally use science, biomarkers, and biofeedback to guide my longevity strategy at 50. As a PhD scientist who studies aging biology, I focus on understanding how the body changes over time and supporting the pathways that influence healthspan, metabolism, and cellular resilience. This approach isn’t about copying someone else’s protocol. It’s about learning how to measure what matters, interpret the signals your body is giving you, and support aging biology strategically. In this video I discuss: • How aging shows up in biomarkers long before symptoms • The lab markers I track regularly (cholesterol, ApoB, insulin, inflammation, hormones) • Why biofeedback like sleep, HRV, and body composition matter • How I use data from wearables like my Oura ring • Why NAD+ and glutathione are important for cellular aging pathways • How I think about supplements for mitochondrial and cardiovascular health • Where peptides fit into my longevity plan • The role of GLP-1 signaling, growth hormone pathways, GHK-Cu, thymosin alpha-1, and KPV • Why foundations like strength training, sleep, and nutrition still matter most Longevity isn’t about doing everything. It’s about doing the right things for your biology and reassessing over time. This video is for educational purposes only and should not be considered medical advice.
