Testosterone
Testosterone is a key hormone for energy, mood, strength and sexual health. Levels can change with age, stress, sleep and overall lifestyle. When testosterone is too low or too high, it can affect motivation, muscle mass, fertility and general well-being. Because symptoms can be subtle or mistaken for other issues, regular testing helps you understand your hormone balance and track changes over time.
