While starting a Deca/Test cycle for 12 weeks, I have a 6 week supply to add 50mgs of Winny per day. Should I add this to the last 6 weeks of the cycle to help with some water cut down and leaning out or first six weeks to kick start the time for the deca to kick in?

I am doing 250mgs of Deca weekly and 500mgs of Test Cyp weekly for cycle. 12 weeks of deca, 14 of test. Arimiex during cycle, PCT set for after.

Input would be greatly appreciated.
