No I wont. I am not gyno prone and have no prolactin or progesterone issues when taking nandrolones. I ran NPP and Tren in the same cycle a year ago - had no issues.
I always use an AI (used to be arimidex, now aromasin) as well as Dostinex with the nandrolones. I have never, after including a nandrolone in 4 of my last 5 cycles, had any gyno symtoms/issues.
