I was also under Dr.Arvind, and I sort of agree with you - partially though. In my case, again, he was not too accurate but then, didnt do much damage either.
And about testosterone level testing - I did it on my own. End of day, medications are more or less the same irrespective of the doctor - as it is not really rocket science. What really varies is each one's body type and their ability to synthesise the medicines. While under medication and over medication are bad, it is also true that this is somewhat of a trial and error process to determine the right dosage.
Yeah, it is also important to have faith in your doctor. No point consulting someone when your mind feels otherwise. So choose someone who you are compatible with mentally and emotionally - and stick to the process with him/her and give it time, I guess.
