Prop esters will still take up to 2 weeks for blood levels to be at their greatest. And some users will still not see effects gain-wise until the 2-3 week mark. For myself it takes right around 12-13 days in to start seeing strength/agression/size come. I would opt for at least an 8-10 week cycle for a short one, and even longer if it was me running it. JMO.
As for dosing the deca the same as test, I dunno, because I've never done it that way.
