I would run Nolva w/ Clomid from weeks 17-20. Fifteen days should be long enough for test-C to clear your system, and you want to run it for four weeks not three.
I wouldn't start the arimidex until week 2 at the earliest, likewise with the HCG. Also, HCG is normally 2x 250iu /wk.
Bloodwork @ wk 6 or 7 would confirm your estrogen is in range but my guestimate is something between 0.33-0.5mg EOD would be approximately right for that cycle.
Make sure you have something like NAC for liver support during dbol wks 1-5 at least; five weeks isn't insane but it's fairly long.
Good luck bro.
Snowpatrol summed it up well, but would go for Toremifene over Nolva/Clomid. I have experience with Clomid, horrible shit gives me floaties (some people get this+visual tracers) and worse depression/anxiety/mood swings than low T gave me (having primary hypogonadism didn't help + Clomid sides so) but a lot of people report this effect from Clomid anyway. Is it effective, hell yeah and it has been proven. But I would go for Toremifene at 120/90/60/60 based on all the reports (admittedly no experience), toremifene appears to have 0 sides and restores the HPTA quite well. PCT should be minimum 4 weeks like mentioned.
Definitely do not run Nolva alone, Clomid alone would be better than Nolva alone in terms of HPTA restoration.
I would also run the AI from the get go, test levels start going up within hours and so will your e2 (why people put on weight in the first week due to water from e2 rising).
IMO, you should be happy with the Test+Deca without the Dbol, I'm more of a less is better sort of guy and believe you should stick to the least amount of stuff you get results and you will also get a chance to see how the deca goes with just the test, Test+Deca+Dbol is a good mass builder however. I would probably up the Test to 600mg and leave the Deca at 400mg though without Dbol.
You should be pleased with Test+Deca at those doses and you can always do the exact same cycle (and expect to still grow with proper diet and training) and throw the dbol in for a kickstart next time.
Also, use
PCT Calculator to work out when you should start PCT... The 14 day after your last Test E/C shot is bullshit and by 14 days you should still have enough exogenous test to keep you shutdown still.
BTW, what did you do to get banned lol?
