Control estrogen and you actually can control, both prolactin and progesterone.
AI's will help control prolactin becuase of the Long Feedback Mechanism, but sometimes dopamine-agonists are needed, so keep one on hand.
The progesterone receptor is synthesis in response to the estorgen receptor in healthy breast tissue. So using Tamoxifen will actually down-regulate the PgR.
AI on cycle, Tamox always on hand and D2-agonist on hand when using 19-Nor's.
