I do it fairly regularly. In fact i run low dose deca with every cycle (150mgs/week) then on a tren cycle ill run high dose tren with it and moderate dose test. Just control your estrogen with a proper ai as estrogen truly increases prolactin. Progesterone upregulates prolactin receptor but NOT i breast tissue. Thats where the sexual sides come in(not prolatin induced gyno like brocience dictatates). For that pramipexole. If heavy tren cycle with low dose deca and moderate test (btw my test is ALWAYS less that my 19 nor dosage)
