how do you know what is particularly causing your gyno? ie. progesterone, estrogen etc.

It depends what your cycle is like, for example: a test only cycle has estrogen sides, while a tren cycle usually has prolactin sides.

Nandrolone is proven to be a progestin, but it also aromatizes to estrogen to some extent. So, you have possible progesterone and estrogen sides.
