I'd extend to 14 weeks because your running deca and Deca should be ran at least 12 weeks and needs a month to clear before pct. SO I would do..
Test 500mgs 1-14
Dbol 50mgs 1-4
HCG-250 IUs 2x a week (this is up to you when to start but stop 4 days before pct)
Have something on hand to control prolactin from the Deca
