I used Vitex toward the end of a Fina only cycle and it helped. But that was because it was PR related not estrogen related. In his initial post he stated nothing of deca. I don't think he should take Vitex just because he is experiencing some gyno symptoms. If he can tell us more about his cycle, maybe we can better diagnose. The Deca can cause PR gyno, but his test can cause estrogen related.
I wasnt saying Vitex causes gyno, what I meant was if it is not PR related gyno, Vitex may just expediate his gyno.
