arimidex will do nothing becuase deca converts to progestone. I am going to be take arimidex though becuase I will have a 1.5gram of test a week on this cycle
Running that much of 17aa's CAN be dangerous. Make sure you have your protectants. I would say that the winny should do the trick, but I've only used it with anadrol, not deca.
I just heard that Masteron has the same anti-progestenic effect as Winstrol. I am trying the chinaman's masteron with my tren now... I'll tell you if it helps (on tren without winstrol my nips get real sensitive and puff up).
If Masteron works it would be a much safer option than either RU-486 or Winstrol.
Tomorrow I'm picking up the article that says this. It is in some anabolic newsletter that a friend of mine subscribes to. I'm hoping it cites actual studies that have shown the anti-progestenic effect of masteron.
