The sides you speak of are not found in everyone. True fina gyno is a rarity and also, bromocripton is not needed even for "progestin" gyno.
Estrogen is absolutely necessary for breast tissue to develop (ie, gyno). knock out the estrogen with nolva and gyno can not progress. IMO, people are too quick to jump on the bandwagon with bromo for progestin gyno. It simply isn't necessary and it is a harsh drug with many sides to boot.
Personally, I did not have a problem with fina dick or immunosuppression or anxiety. Of course, I took test prop with it so that may have been the reason for not getting fina dick. I did have the night sweats pretty bad and a little insomnia. I also gained nearly 30 lbs on my first cycle at 50 mg a day.
Bottom line, you don't know how you will react to anything until you try it. The good thing about fina is that it is short acting so if you have a problem, you can just stop and it will be out of your system in a week.
