Capergoline is Dostinex. One thing to be aware of when taking it is that some of its side effects may overlap with some of those typically attributed to trenbolone acetate, such as shortness of breath/chest pain and persistent cough, as well as difficulty breathing when lying supine. Breast pain is also reported, which may overlap with some of your gyno symptoms.
Tamoxifen (Nolvadex) always worked best for me if I started it as soon as I started to notice any peri-areolar soreness. This is making the assumption, of course, that the symptoms are estrogen-related and not prolactin-related.
One reported "side effect" of Dostinex is greatly enhanced volume of ejaculate. I've never taken Dostinex myself, but wonder if anyone here who has used it noticed that. It has been reported that porn star Peter North, famous for big blasts, used it for that purpose.
