I've always told everyone that if you seek medical treatment and advice, you should listen to everything your doctor tells you to do. If you disagree with his/her treatment, you have two options. Find another doctor, or learn enough to manage the shit by yourself. This stuff really isn't rocket science. With a little time and to learn how to properly use AAS and read/understand your blood work results. You will be just fine...better than "just" IMHO. There are dozens of guys here that are suitable candidates for TRT treatment. The only reason why I went to a endo here and in Europe is so that I can have a script on me for when I'm traveling with oil and pins....because IMHO, I think I know a little more than my endo when it comes to using different types of AAS for the purpose of body building, not just for the purpose of keeping my free test within range. Most of the vets here know A LOT more than most doctors when it comes to this type of material.
For example....the OP said he was worried about testicular atrophy. That is a VERY easy problem to fix if you take a little bit of time to learn the ropes. Should the OP decide to up his doses, he should familiarize himself more with AIs ans SERMS. And at the same time, learn how to properly train and eat. When you go to an endo, he isn't going to give you advice as to how to eat properly and how to train. Like I said, I go to an endo every so often just to have a script....and I go when I know my numbers are way too low. Do the shit on your own brother, doctors will not help you put on mass and size like you want, they will however give you what you need so that your test levels are that of a normal male....but that isn't really what we want, right? Learn your shit, read all the stickies and as many of the threads on this board as you can....and in a few weeks time, you will know more than your endo when it comes to body building. These doctors don't go to school to help you learn to use steroids in the fashion that suits us best.
Study your shit, learn as much as you can, and you will be more than fine. You just have to have the will to take the time to learn the science behind it all. Don't be one of those fools that just wants to pin as much oil as he can just to put on the size and completely ignore diet, training, AIs, SERMS, etc. I would first start in the kitchen and in the gym. Learn on what you should be eating and how you should be training. Than move on to the rest of the stuff. Read every profile for every compound out there, be it an AAS or an AI/SERM, etc. Good luck. Oh, and one last thing....I say this because my best friend is also my primary MD. He trains just the way I do, and uses anabolics all the time. If he has a question or a concern, he'll give me a call up and straight up ask me if I can help. Just think about it, my primary MD (who has been my best friend since high school) is calling ME up for medical advice. He knows his shit, but sometimes he'll give me a ring and ask me my opinion on a stack he's putting together. I just find that funny as hell...and I love busting his balls about it! lol I don't have any kind of MD....just a bro science degree!!! lol
