I would go for 12 wks 500/mg a wk and run 20 mg of nolva from the start to keep the water retention down. You could adjust this up to 40 if needed. Regardless there is going to be some water gain. The for your PCT
run
nolva 40/40/40/40
clomid 150/100/100/100 you will be gtg

250 is probably a wast of time
