More likely than not 200 mg a week is not high enough to cause gyno, but to very sensitive and/or prone individuals you may get some symptoms anyhow (though highly unlikely imo, I consider myself gyno sensitive and I still have to break about 600mg a week to see gyno sides). May be worth ordering some arimadex or nolvadex (not as quite as effective but MUCH more pleasant than arimidex side-effects wise and cheaper, and unless if you're shooting a gram a week nolvadex should do just fine).
I'd ask your doctor if he can prescribe something just in case..... but with the medical racket in the US nowadays it may be exponentially cheaper just to order it on your own (same with the test).
Gonna cut myself off there before I get on a rant on the US medical industry....
