Hey bro, first, if you use deca, you want to use it with test as the base of your cycle. Test E, Cyp or Sust would do fine. As for combating proges and prolactin, winstrol is not the answer. Winstrol is a DHT based steroid. Its main benefit is give the muscle a dry look at the end of a cut cycle. What you would want to have on hand is caber. Caber dosed at .5mg 2x wk should be enough. I would suggest you hold off using it though. Have it on hand and then only use it if needed.
