As men age, their bodies naturally experience a decline in testosterone production, leading to symptoms like decreased libido, fatigue, weight gain, and depression. While TRT has become a popular solution for men looking to regain their youthful vitality and improve overall health, it may not be enough to achieve optimal results on its own. Some men might experience side effects like acne, hair loss, and an increase in red blood cell count when using TRT alone. Moreover, TRT may not address other underlying health issues contributing to aging symptoms and weight gain.
