Low testosterone is sabotaging your health, motivation, and long-term vitality—and diet alone won’t fix it.
In this episode of The Human Upgrade, Dave Asprey sits down with Shalin Shah, CEO of Marius Pharmaceuticals, to break through the testosterone misinformation that’s kept millions suffering. They unpack the real causes of the global testosterone crisis—including endocrine disruptors, poor sleep, processed food, and outdated fears around steroids and toxic masculinity.
You’ll learn why testosterone matters for both men and women, how it powers dopamine, mitochondrial health, sleep, libido, and mood—and why “natural” testosterone boost methods usually fail. Dave and Shalin reveal how biohacking hormone health is evolving, and how new oral testosterone therapy (Kyzatrex®) is rewriting the rules with safer, more effective delivery—no injections, creams, or risky side effects.
