Probably had an issue before this that has not been mentioned or known of.. just takes a little bit to spark it.
50mg of DBol is a lot for most people, and that can cause an issue quick.
If you turn out to be really prone to gyno and other estrogen related sides, you are going to want to stay away from steroids that convert to estrogen.. like the ones you are running.. going forward. 300mg Test and 20-30 Dbol will yield plenty of results.
