200 mgs/ week is the upper dosage of TRT. An AI is only needed if you are suffering symptoms of high E2. Things like gyno or other related issues. Did you pull labs pre TRT, during TRT? To check E2 levels before just adding in a compound? Injecting twice a week subq is the best approach and helps to stabilIze serum levels which helps keep E2 from getting out of control, but everyone is different. Are you taking HCG with your Test? Have you been pulling labs to check you RBC? And Hemotocrit levles? With that high a dose you could have polycythemia, very easily. I take 150/ week and def have it so, that is no joke and why you should be pulling reg labs.
Typically pct will start 2 weeks after last inj ( depending on ester). Pct is clomid and nolvadex Not more test. Pct runs for 4-6 weeks depending on compounds taken on cycle. So in your case 12 week cycle + 2 weeks waiting for pct + 4-6 week pct = 18-20 weeks to complete first cycle and pct. THEN you need to wait 20 weeks before beginning another cycle What you are proposing is wrong in so many ways. Scrap that and start over
