I would split the 400 mg/week of test into two shots, monday and thursday. Since your only doing 200 mg deca(not much of a dose) you could either do 1/2cc with each of your test shots or just do them every monday in a diff. location than your test shot. Personally I like to keep my blood levels more stable so I would do the 1 cc test 1/2 cc deca every monday and thursday, and make sure your alternating locations.
