Hey bro, looks like a good short leaner! It's my first inclination to say you probably needn't worry about gyno, but we all react differently to different "treatments" and if you're prone, then it'll definitely behoove you to have some arimidex on hand. In fact, it would be even better if you tossed some HCG into that cycle, and added on arimidex at 0.5mg EOD (that may even be excessive, but I'm just erring on the safe side considering hcg can exacerbate estrogen levels). My thinking here is that with a cycle that's moderately light and as short as 7 weeks, you're already going fairly easy on your HPTA. So why not take just one tiny extra measure to make recovery that much easier and that much quicker? Then you can hop right back on after less than two months off and not miss a beat!
Also, I'd up the proviron to 50mg if you have the resources to do so. I just don't know that 25mg ED will contribute much when you're already running solid doses of prop and winny. Then again the only time I take orals is when I want to BLAST them, and that's not always appropriate in every context, so it's your prerogative. Since you have experience with cycling, you're obviously a better judge of your own body than I am!
Cheers and good luck!
