Cyp is a day or day and a half shorter than enanthate. This is incorrect. Cypionate ester is about 4 days LONGER than enanthate.
You aren't doing enough test to warrant your AI dose. You could more than likely run the entire cycle without running an AI at all, unless you are prone to gyno, which you won't know this being your first cycle. Also, you want to be able to recognize gyno symptoms if you plan on juicing for any long term periods (I.E. cycling), so personally, I wouldn't run the AI until I notice symptoms, then run .5 EOD for a week, then stop using until symptoms appear. The above advice is not recommended, especially for a first time AAS user. If you're unaware of how sensitive you are to exogenous testosterone, the best advice is to include a standard beginners dose (.25mg EOD) and monitor from there. This way you are not completely at risk of rising E2 levels and their associated sides - some of which are more damaging, potential fatal, than gynecomastia. It will also send your endocrine system onto a roller coaster ride if you administer your AI up and down like the above suggests.
I have found no practical application to have my clomid double dosed, or to double the dose of nolva beyond the first week.
I would also run a bottle of test p at the end of your cycle, to help keep your bloods stable while you wait for the longer ester to clear your system. If you go this route, after you finish the prop (run it @ 100 mg EoD, for 3 weeks), you can start PCT 3 days after last pin.
PCT dosages should look like this.
clomid 50/50/50/50mgs
nolva 40/20/20/20mgs
