Tren increases PROGESTERONE levels(not Estrogen) if I'm not mistaken, so I don't see the point in adding Nolvadex quite frankly brother. If you buy into Winstrol-V being an anti-progesterone hormone, then that'd be a better choice.
If you're worried about your P-R-O-S-T-A-T-E

D) gland, then you could add Saw Palmetto, Zinc, or Lycopene.
