In this episode of the Healthy Living Scottsdale Podcast, Coach Zach and Coach Jolie dive deep into hormone replacement therapy (HRT) for men, with a primary focus on testosterone. The conversation covers how testosterone functions in the male body, the critical role of free testosterone versus total testosterone, and why both numbers — along with sex hormone-binding globulin (SHBG) — matter when evaluating hormone health. The hosts discuss the growing problem of younger men in their 30s experiencing low testosterone, often linked to lifestyle factors and exposure to endocrine disruptors like plastics, fragrances, cleaning chemicals, and processed foods. They outline common symptoms of low testosterone — including low energy, poor workout recovery, decreased libido, mood changes, and increased belly fat — and stress the importance of confirming low levels with multiple blood tests before starting TRT.
