I would look at Adex long before Deca as well. I avoid AI unless I actually start to experience symptoms. I don’t ever take AIs as preventative.
It isn’t that they are inherently bad, but they can really turn things in their heads and can be difficult to dial in. You may have crashed your estrogen which absolutely can give symptoms you described.
Reality is you dumped a lot of stuff in without understanding dosages or modes of action. Result is you are having issues and don’t have bloodwork to help you fully understand what is truly the likely culprit.
At this point you should dial back to 500-600mg if still on blast or 200 mg/Wk of test cyp if on cruise and drop all other compounds and ancillaries.
Then _next_ blast add (1) compound and (0) ancillaries unless you get itchy nipples. Then do .25 arimedex 2x/week at most. (I would recommend nolvadex first if you are a high aromatizer)
Most people shouldn’t need any AI at typical blast dosages.
Experimenting is fine, but it should be controlled to understand impacts. Finger licking and sticking it in the air method is always a disaster.
