Ten years ago, "anti-aging medicine" was synonymous with unproven claims. Today, the longevity space is one of the most heavily funded areas in biomedical research, with billions invested in understanding and reversing the specific molecular mechanisms of aging.
The evidence base for NAD+ therapy is particularly compelling. Sirtuins — the enzymes that regulate DNA repair, cellular stress response, and gene expression — require NAD+ to function. Activating sirtuins through NAD+ replenishment is one of the few interventions that has consistently extended lifespan in animal models. Human clinical trials are ongoing and results to date are promising.
For testosterone, the evidence is extensive. Decades of research confirm that optimizing testosterone in men with clinically low levels improves muscle mass, bone density, energy, cognitive function, mood, and cardiovascular markers. Physician-directed TRT, appropriately dosed and monitored, is not a performance enhancement — it is physiological restoration.
At Viva, longevity medicine means something specific: physician-supervised protocols, evidence-based treatments, and honest conversations about what we know and don't know. Dr. Cordova brings his background in critical care medicine and biomedical engineering to designing protocols that are rigorous, not trendy.
