IT'S NORMAL for levels of testosterone to change depending on things like age, time of day, sexual and physical activity, and overall health, but consistently high or low levels may cause some unwanted symptoms that could slow you down in the gym and in bed.

Testosterone levels in adult males naturally decline as you age (about 1 to 2 percent each year), but testosterone deficiency in men has become a larger focus of the health community in recent years. Testing your t levels can provide more info on your sexual function and drive, muscle mass development, mood, energy, and even the production of red blood cells. But lab tests can be costly and a pain to schedule, so at-home test kits could be a great starting point for learning more about your T-levels.

Important: not all at-home test kits are created equal. For starters, they're not as reliable as health providers' lab work—your at-home kit's results could vary based on the quality of sample collection, and how you well collected it (yes, you need to read instructions!). Here's the 101 on what to know about at-home kits that are available.
