I would substitute the deca for something else personally..like masteron enthanate or maybe some oral like Dbol or winstrol.
But if you don't feel like doing that I'd run deca anywhere from 400mg-800mg each week. They should be injected twice a week (monday and thursday is the typical schedule).
I would frontload both substances, anywhere from 500mg to 1g each on the first shot.
Use adex .25mg-.5mg every other day
pct should be nolva 40/40/20/20 2 weeks after last shot of enthanate
Deca should be stopped before the testosterone because it has a longer ester.
also consider caber to lower prolactin levels.
