Either - Dbol will work great with both.
I like the Deca combo since the dbol is already very androgenic - I like to play it safe, maybe do Deca for 6 weeks and Dbol only in 1-4 since you seem limited on the Dbol. You could get away with 200mg of Deca in weeks 1-5 which would taper through week 6 and on a bit.
This board seems to love adding testosterones to everything so you'll probably get a lot of responses the other way. To appease them if you do go with the deca at least put some Sustanon on your breakfast cereal in the morning. It will make everyone feel better.
