It depends on how high testosterone affects your body. For example, if you experience increased sexual desire, muscle mass, strength, energy, and endurance, then you may see the high T levels as good for the body.  Increased testosterone can be a good boon for those who want to get bigger, faster, and stronger. But, when the excess testosterone is causing you health problems, such as liver problems, acne breakouts, high blood pressure, low sperm count, or prostate enlargement, then it can have a negative impact on your overall health and well-being. Talk to a doctor if your testosterone is causing you problems.
