I would say 12 weeks straight with orals, 5 weeks d-bol and 7 weeks winny, are going to be tough on your lipids and liver. I would either drop one or the other or adjust the placement at the very least.

With a test blend you will have a longer ester test that will run 2 weeks past your last injection before you start PCT, so you could move the winny out a bit as follows:

D-bol @ 50mg weeks 1-4
Winny @ 50mg-75mg weeks 9-14
Week 15 PCT

I would also add milk thistle and NAC to your liver protection supplemts along with 10g of fish oil and policosanol 20md daily for your lipids.
