Happy to help Bean.
These are just pointers on how to set it up.
The actual layout of the cycle depends on cycle experience, how long you've been training, and how you will train & eat.
Remember, you got only 20mL test prop total, which will give you 40days of EOD pinning; thats 5,7 weeks.
So you don't have enough test prop to run through entire cycle, unless its gonna be short.
The nandrolon stacks well with either test or winny, but deca shut you down hard,
so I would run it in the beginning. On top of that its nandrolone decanoate, a very long ester.
A prime example of fucked up PCT is running a long actin ester up to the PCT. Blood levels will then be supressive well into the PCT.
Calculate a 7-10 day half life for deca to be on the safe side (it will vary depending on injection site)
I know from experience that blood levels after a heavy cycle (with long esters like decanoate & undecanoate) can take over 4 weeks to reach non supressive levels.
You might look into getting some more test prop, or you'll either have to run a 6weeker,
or you'll have to run some part of the cycle without any test.
Usually when running a 4 week winstrol cycle at the end of a test cycle,
the test was long estered, so blood levels of test is still there a couple of weeks in.
When I stopped test (enanthate) and just ran DBOL I was fine for the first weeks,
but then I really started to feel like shit.
Great for cutting though, without even the natural test your estrogen levels drop to nothing,
and you can obtain a very vascular look. You will feel like shit however.
With Winstrol it should be even worse, since it doesn't aromatize at all,
but you will lose both water weight and stubborn fat.
