Couple things:

What is your current BF%? (approximately)
You need a sensitive E2 assay, not estradiol.

The amount of adex your are taking is more that the normal amount used on cycles of 500mg + Test per week. Why do you or your doctor think you need so much? You need to get on a twice per week protocol and probably titrate your dosage down a bit, quite honestly. You will maintain more steady levels this way and have less of a spike in estrogen. Less injected at one time = less spike in E2. Therefore, easier to manage.

As referenced by Brett above, adex is best taken the day after test injection which times the peak of the test allowing you to get by with less adex, which is your goal. You're also on the high end with HCG. IMHO you'd be fine titrating this down as well which will help with intratesticular E2 that adex doesn't control. If injecting 3 X per week with HCG timing with test shots is irrelevant. Simply go M-W-F.

Get on a twice per week protocol as it will help you. Also find a way to reduce your adex as it's really a ridiculously high amount for an HRT.
