Keep the AI on hand man, that's what I do. I've run up to 1.5 grams of test/week with Dbol and had no Gyno sides and didn't use any AI.
You'll have itchy/burning nipples long before you get any gyno, and check your nipples before the cycle to make sure there aren't any bumps and check it every week or so to make sure nothing develops. You should be good to go.
Gyno is strange and can spring up any time, it's always good to have every ancillary you need on hand. AI, and SERM.
Your HCG usage is good, using it throughout the cycle is what I would do.
