Hey just to weigh in...
My TRT is 125 mg every week - everyone is different.
I actually pin every 2nd day 35mg. I got used to it. I pin sub Q with slin pins. Easy, painless, but takes a long time to load so I warm my T vial under warm water.
My levels are totally steady, I feel great, and No AI. When I was pinning 125mg once per week I felt like shit for the first couple days. Water, E2 side effects - it sucked. Splitting my dose has made a WORLD of difference.
You MAY still need an AI at 200mg - as I said everyone is different but I would highly suggest splitting your dose up. Took me 8 months to dial in my TRT. Now it's awesome!!
Hope it helps. Reach out to me if you have other questions, I'm pretty analytical and have prob. Read everything there is on TRT - anactdotal and medical.
