Yes this is a lot of gear for a second cycle. When you say parabolan, you're speaking of tren hex, I assume. 600mg of tren is a high dose, by competition standards, not to mention, someone doing their second cycle. Also, winstrol at 100mg is about 2x what you should need. I think that this whole plan needs to be dialed back. If this is your second cycle and your goal is to cut, test cyp or test 5 at 500mg for 12 wks, along with Winstrol oral 50mg ED for the last 6-8 wks, should be more than enough. I'll break down the dosing, but lets back it up even further for a minute. If you didn't make good gains on your first cycle, something was very off. I would expect that you put on (depending on your current size) 20 plus lbs in 12 wks and kept at least 10 lbs. If you weren't able to do that, your diet and possibly your training was off. If you don't have the diet on track, the gear does not work. So please, be aware of that, going into your cut. The gear you use on your cutting cycle isn't going to get you lean. It will help you maintain muscle, while losing fat through diet and cardio. If you don't have those things in order, 12 wks down the road, you are still going to be fat. So get to researching what you need to do to get lean. You need to figure out how much you need to eat, in order to maintain your muscle, first off. Then once you have your protein figured out, you can manipulate your carbs and fats to lose or gain muscle.
As for your dosing, here is what I would do :
Test E or Cyp 500mg EW
adex .5mg EOD
Winstrol oral 50mg ED
PCT starts 2 wks after your last shot.
If you have the diet figured out, adding in some clen will helpw ith fat loss
