While testosterone levels differ from person to person and fluctuate throughout the day, normal levels range from 300 ng/dL to 1,000 ng/dL. The best way to determine your levels is to meet with a healthcare professional. From there, these lab tests can be ordered to analyze the amount of testosterone (sex hormone) produced by your body. When levels are low, it can cause a series of health problems. Board-certified general surgeon Eric G.
