No offense to anyone but if you use AAS's and don't get a total lab work up done then you are using irresponsibly. I get work done pre, during, and post cycle. Internal damage isn't a guessing game. It is the difference between being healthy and dying in your sleep. I get copies of all my lab work too. My doctor is cool like that. If yours isn't then find a new one. I can tell you my liver values, cholesterol, BUN levels, RBC, WBC, birilium levels, name it I have it at my disposal. JMO.
