Introducing Tren A into cycle

I was wanting to add Tren Ace into my next cycle which will be my third cycle. Is it too soon for Tren? I've read it's for more experienced users but I'm a little unclear as to when one is considered experienced. My first two cycles were the following:
Cycle 1
Weeks 1-8 test prop 150mg eod
Weeks 1-8 aromasin as needed
Weeks 9-12 clomid 50mg ed
Cycle 2
Weeks 1-8 test prop 150mg eod
Weeks 1-4 dbol 50mg ed
Weeks 1-8 aromasin as needed
Weeks 9-12 clomid 50mg ed

Cycle 3:
i was wanting to do cycle 2 over again but adding Tren. Is this a good or bad idea? If good what ratio of prop to tren should I use?
