test anavar cycle

my stats are 26 yrs old and 5'8 12stone with 11% body fat. this is my 2nd cycle, I'm on my 3rd week right now and doing so far 1.5ML of test and 40mg a day anavar. I want to switch the var to deca next week and then switch back to var as a finisher. I want to keep the stack healthy. opinions?
