how are you breaking up the winny per day to get to 300mg?? thats not important, I was just curious?? I'd up the deca to at least 300 if not 400mg per week. \Do the winny at 50eod, through out and that will protect you from the progesterone induced gyno from the deca.. look out for deca dick too... the winny wont help you there..
Do it like this, shorten in to 8 weeks, and take the winny eod for all 8 weeks too.. at 50 mg eod 8 weeks is not that bad.. just remember to take your liver helpers and drink lots of water and you'll be fine.. but really... up the deca to at least 300..
