With that gear and in those amounts...I would do a 7 weeker (so you have winny/fina the whole time)- actually I would do 50 days like so:
Fina-37.5mg/day or 75mg/eod
Winny: 50mg/day
Test 250mg/week
You won't need arimidex (which will save you money), and you won't be puffy or retain water.
If you are a bigger test fan than I am (and odds are, you are, lol), then up it to whatever level you are comfortable with. However, you will then need to add the arimidex.
