Winstrol, even supposedly helps with progesteron receptor binding induced gyno, doesn't help everyone. Many guys got signs of gyno or some even actual gyno on Fina only cycles. The greatness of Fina comparing to Deca in that sense is that Fina is so fast acting that you can just simply stop using it, and halt gyno devellopement.
Anyway, your chances of getting gyno with your dosage are next to nothing, may be 1%, but because you are using also dbol and Test, make sure that you are prepared for estrogen induced gyno.
Like Stew said, Arimidex, Cytadren, Nolvadex all will help. It's good to add Winny, because even if it doesn't work for you as progesteron receptor selective antagonist, it works very well in stack with Fina, and is very good steroid overall!
