Never heard of bromo either....all the threads i read pointed to letro....and i read a lot of threads.
Bromo will be hard to find (not that it's not a good line of investigation), but you'll have better luck with cabergoline, also fairly expensive but easier to get. Cabergoline (dostinex) is a dopamine agonist / prolactin antagonist. If your gyno is progesterone-related cabergoline will help where Nolvadex could make it worse.
Letrozole, BTW, is also purported (brotelligence, maybe) to help reduce progesterone, but killing estrogen is what's critical. No estrogen, no gyno. Letro is extremely effective at lowering estrogen levels, however you'll either want to taper or switch to a steroidal AI (Aromasin, ATD) to avoid rebound. Search on the drug name here at AM if you want more info, there's excellent information here from some very smart people, which I won't attempt to reproduce.
BTW, it is very hard to give advice without knowing what your blood levels of these hormones are. Understand that my "kill estrogen" advice assumes that your levels of this hormone are in fact elevated (which I do think likely), but you'll have a hard time knowing whether they are improving, how long to remain on, and how to adjust your levels without bloodwork. It's not something you're going to want to do forever, as the hormone, and it's balance with other hormones, is important for your long-term health. Your getting good advice from the members here, but none of us (I think) are doctors, so take it for what it is.
My overwhelming advice to you is that you seek out a doctor that is qualified in this area. You are probably looking for an endocrinologist, preferably one that has worked with athletes, as they may be more likely to have encountered and treated steroid-induced gyno in the past. If you live near a University with a decent athletic program, that might be a good place to start looking.
I don't know what your situation is, but I would skip my GP and Insurance company (if GP referral is required), and going right to an expert in this area and pay cash. Sometimes people are afraid to bring this stuff up with their GP, but I don't think you have time for that, you need to attack the problem head-on. Tell the administrator that it is an emergency and that you will take the first available or cancelled appointment, come clean with the doc right away. In this manner you will get the care you need quickly and professionally, without creating any awkwardness between you and your GP. An office visit will cost you about 200 USD where I come from, but so will two vials of Aromasin shipped from a research site. If your insurance covers scripts, you'll be able to get high-quality legal medications under a physicians care and the cost differential won't be that great.
Good Luck -- Last post, I promise (unless someone flames me).
