This is hard to answer, alot of variability here. On Anastrazole, I'd start low (sub 1mg/week) and get it rechecked. At 150mg test per week I crashed mine w 0.5mg Anastrazole just to let you know how potent the shit is. You will feel like absolute dogshit if you crash it. Only smart way to know how much is by taking a conservative dose, and checking it after a few weeks. Also, pin your test 2x per week at a minimum for less e2, a large bolus dose always aromatizes more than smaller, more frequent doses.

I’ve noticed arimidex is a little stronger for me even tho it’s not a suicidal inhibitor like aromasin @Teeeethreee said it best, less is more with an ai. I’d try to lower it with eq primo or mast (low dose) first, as ai’s really aren’t healthy to use and should be used sparingly. The less the better, and your e2 is higher end but def not astronomically high either. E2 is also relative where people feel best at. Remember it’s more about the ratio between test and e2. E2 IS ANABOLIC and NOT the enemy, clearly you don’t want it too high but it is something I’d rather have high of any day over crashing it

Remember always treat the symptoms not the numbers. Arimidex .25 every 3 days if you start negative sides then work up from there. Aromasin 6.25mg every 3 days.

Less is more. Try 1mg every 5 days of Arimidex. Even that may be too
Much lol just keep an eye on how you feel.

Have you noticed any symptoms such as an increase in blood pressure or nipple sensitivity? I've not used an ai before but whenever my nipples started acting up - which may or may not have been in my head - I just used tamoxifen at 20mg daily.

How about eq, mas, or primo?

Those are the same thing. Arimidex is the brand name of Anastrozole... the fact you don't know that probably means you shouldn't be on gear. Not only not knowing those two are the same, but not knowing what they do or why, or what AI or SERM you need to take for what or what the difference between the two is.
