No real right answer - some docs take PED's and will discuss it, but in general no - most are not taught well about hormones (based on my experience). You run the risk of being a patient with a medical file (front page - uses steroids) that will lead all doctors to believe many medical issues, that have nothing to do with being bigger/more muscular/on PED's, are caused by this. Take a person with higher ALT all the time which is indicative of long term liver damage vs GGT which will go up with a few drinks or Tylenol & fatty liver (just a few causes of GGT, but is considered the most sensitive liver test and just one small piece of the overall picture of your liver health). You work out, have more muscle mass hence doctors don't order an ultrasound or do further blood work. It is remiss on the part of the doctor and hope on the side of the patient. Meanwhile you could have inflammation (which may lead to permanent damage) or damage in you liver already that will not get better if you don't remove the cause or try to treat it.
High BP and they know you take steroids - many docs will tell you stop taking PED's / just like they will tell you to stop smoking, but most will give your BP meds. Many patients can hide it - you are just a naturally larger guy who works out and doctors don't understand PED's, but there comes a point where it is really is hard to hide it. Take a 270 lb man that is muscles, vascular, and has a small waist - could be the 1 in 1,000,000 that can do it naturally, but most are clearly taking something.
My creatinine was a few points over normal and my doctor say many with more muscle have this issue and if you exercise a lot - this can cause it. It is back to normal, but he is testing it every 6 months know to ensure it is not something creeping up as many huge people who train like professional athletes have normal creatinine and liver enzymes.
I recall seeing an endocrinologist regarding TRT and fertility issues - on prescribed TRT, his exact letter to my GP, which I have a copy of - ..... claims he has does not used steroids and never abused them. In other words he did not believe me. Never once did he tell my shrunken testes and TRT caused Azoospermia. Hard to fathom, but fact.
If I was going to discuss any PED usage with a doctor, I would get to know them, talk about injuries and healing, TRT and concerns and how you feel and see what their take on the subject is. Discuss side effects and the fact you work out, but keep getting injured and hear people talk, but care about your health. See if it goes anywhere. Most doctors are becoming very open with people. I heard my old doc talking to people in the hallway, if you don't quit soon you will end up coughing up pieces of your lungs. Ever wonder why the world's leading cause of cancer deaths has 1 day to promote awareness compared to the less lethal types, but just as important, have over 30 days a year. Why - you did it to yourself if you smoked.
I would not go down that road without knowing the doctor well.
