Hormonal

Testosterone replacement therapy in men with acquired hypogonadism significantly increases spinal and trabecular bone mineral density (BMD) and lean muscle mass while decreasing body fat percentage over 18 months.

If you are a man diagnosed with hypogonadism (low testosterone), testosterone replacement therapy (typically 100mg/week) can significantly increase your bone density and muscle mass while reducing body fat over 18 months. This treatment addresses the underlying hormonal deficiency, leading to measurable structural improvements in the body.
