My response is a little all over the place, so bare with me :

Some people are more prone to bloating than others. If you tend to bloat a lot, NPP at 450 per wk and 800 EQ is probably going to have a similar effect to using other compounds you have tried. It's hard for me to instruct exactly what to do, since I have no idea what your diet looks like and have no clue what you actually look like, in your "bloated" state. It may require a cleaner diet. It may require less gear. It may require understanding that fluid retention is part of the process of growing. Hard for me to say without more direct data, pics, diet, ect. If you really are getting badly bloated, to the point that you have high BP and are straining your heart and kidneys, it might be in your best interest to reduce the doses. Part of genetics in bodybuilding is our tollerene to gear and we have to respect our bodies. Some guys can handle high doses with no problems, while others have side effects just looking at gear. If it's an aesthetic issue and you wanted to stay lean looking year round, you can always run a low dose of test with Masteron or Primo. Your gains aren't going to be nearly as good as they could be, but it's all about your goals and what you are willing to go through to get there. You don't need as much as some people would think. If your diet is big enough, you can gain on test/primo, and look pretty damn good! Then again, eating enough to make gains is going to cause water retention, even off of gear. Add gear, which is known to cause mineral retention, and you are more certainly going to lose some shape. 

As for the orals, M1T and Sdrol are both pretty toxic. I would pick one or the other and run it for a few wks, while your NPP kicks in. M1T is more likely to cause water retention IME. Also, you may find that you suffer sexual side effects with such low dose test compared to the NPP and EQ. I have seen either compound cause problems for guys. Hopefully the dostinex is enough to correct that.
