Just take the Arimidex, man.
"but I didnt need it in the beginning"
I also didnt need BP meds until I had high BP. Now I do, so I take them. simple as. No reason to make yourself suffer because "in the past i could do it without these meds"
arimidex allows you to raise aromatase a bit quicker when discontinuing it/ lowerig the dose, plus its cheaper so I would go with that.
I beg you, just pin the test, bro. TNE is fun, but it gets old quick if you do it 5x/week for months. You dont want to ruin one of the best PWO compounds for yourself just because you dont wanna run an AI.
Make it easy for yourself, make it enjoyable for yourself. No coping, no overthinking. No overcomplicating.
also, congrats on the wife and kid, man.
