Low testosterone is sabotaging your health, motivation, and longevity. Diet alone will not fix it.

In this episode of The Human Upgrade, Dave Asprey sits down with Shalin Shah, CEO of Marius Pharmaceuticals, to expose the truth about testosterone decline in both men and women. They break down why testosterone is crashing worldwide, why natural fixes almost always fail, and how the latest science finally makes testosterone therapy safer, simpler, and more effective than ever before.

You will discover why testosterone is essential for dopamine, brain function, sleep, muscle, libido, and mitochondrial health. Fixing your levels can reverse fatigue, brain fog, poor motivation, and slow aging itself.

Shalin reveals how new oral testosterone technology (Kyzatrex®) overcomes the dangers of old therapies and restores natural hormone rhythms without needles, creams, or dangerous side effects.
