Despite its reputation as a "male hormone", testosterone's role goes far beyond defining male traits like facial hair and a deeper voice. It's a critical regulator of metabolism, a key supporter of muscle and bone health, and a significant driver of mood, energy and libido.

Testosterone production ramps up from birth into adulthood, peaking in your 20s. But after age 30, levels begin to decline. This isn't just a minor shift—it's a biological change that can impact athletic performance, energy, and overall vitality. Left unchecked, falling testosterone can result in reduced muscle mass and a higher risk of cardiovascular issues.
