That's nearly perfect, if you're feeling good I'd let it be. You are one of the ones that is sensitive to the estrogen lowering effect of primobolan - without the primo that estradiol value should be much higher on just 1mg anastrolze per week. Little of your free test is getting aromatized right now, so increasing the AI by 50% might well crash it.
If you think you might feel better if it were a bit lower, and assuming you are using anastrozole tablets, you could also make them into liquid solution using alcohol and tweak the dose very sightly, i.e. increase by 0.1mg per week. Unfortunately this drug is so potent and half life so crucial, and the API/filler ratio in tablets is so low, that micro adjustments are just not feasible. This is one of several reasons I find aromasin a much better choice for men.
