To try to answer the questions asked so far:
To reaper33: It was totally catching it at the right time. I remember one of my nipples being puffy for a couple of years, but it was just like the real growth started happening all of a sudden earlier this year. I can still remember the day I noticed something wasn't normal like it was yesterday. I can't seem to find my before pics right now, but they wouldn't be extremely relevant. They were taken almost 3 months prior to starting treatment and I had subsequently gotten worse by the time I actually started the therapy. In the couple of months I've been on the therapy, I've gotten back to around the point I was when the pictures were taken and I'm getting better weekly. I had puffy nipples and just general breast growth behind the nipple and areola. It's actually been hard for me to gauge the improvement myself (I'm my own worse critic), but my mom (who is a nurse and has helped me a lot in my personal research) noticed a difference in just the month between Thanksgiving and Christmas, and said she really couldn't notice it through my shirt anymore, and I was actually wearing a t-shirt during Christmas, and then my endo acted almost shocked at the progress when I saw him a couple of days later.
AndroGel is a topical testosterone gel that is dispensed in a prepackaged bottle with a metered pump on top. Your endo will prescribe you with a certain number of pumps per day, and you just dispense that many pumps into your hand and rub it into your abdomen, and it absorbs over the course of the next few hours. It dries in a couple of minutes and after that you can put on a shirt and go on with your day.
To 30yrold: It was almost 2 months after I first saw my endo that I finally started on my TRT, and that period was one test after another for that whole time, everything from bloodwork (three different rounds if I remember right), to MRI, and even a semen analysis to check testicular function. Everything, other than my testosterone levels, came back completely normal. He started me on a low dose of testosterone for the first month to make sure I was going to absorb it properly, and when that bloodwork came back normal, he upped my dosage. The whole time (and even now) he really hasn't known what is going on, but he has figured out what it isn't and made the call that TRT should work...it has, in a big way. Beyond my gyne, everything from my energy levels to my moods have gotten a big boost.
For everyone else who has asked or is wondering: I live in Montgomery, AL and go to Dr. Neil Schaffner. He's a great Dr, has a great bedside manner, and is extremely thorough. The only gotcha is that he doesn't take insurance, but his staff does help you with the paperwork to file your claims separately. He is $150 for the first visit, and then $75 for followups, and he doesn't make you come in for a bunch of unnecessary followups. Anything he can do with you on the phone, he will, and he won't charge you for it. His lab is separate and does take insurance, so there are no worries about huge lab bills either.
