Curt2go is a good guy (who can't use the return key) and will not plug bdcnutrition.com as he has/had a working arangement with them. Good source if you are unclear about doing a homebrew. See curt now you don't have to feel cheesy.
Keep the 4-ad low at first as it will help with gains, the little bit of est. should not be a problem at all, its supposed to be there.

The advantage of 1-AD is its easy and just as effective as 1-Test (generally). That is not to say its the same as 1-test/4-ad, but most people who have done 1-AD only and ONE only have reported very close results.

Also get your recovery supps before you start, if you start to see a problem - add them to the stack as they will block the est. and you should be able to finish safe and bigger
