pct help w/ 15 week cycle

[DaPit26]

I've never done pct before (never had any problems) but have never ran anything over 10 weeks. I started with ara-test 2500 then fina and about 2 weeks ago d-bol (plan on ending in about 3 weeks) that will make up 15 weeks. I'm going to start nolva and hopefully get my hands on some hcg. I just don't know how much time to take off between this cycle and my next (EQ 400, deca, d-bol) thanks bros for any advice and K to you
