250/EOD * 3.5 EOD/week does not equal 1000iu/week
"as long as the hCG was before the T Cyp" = baloney
Your AI should be closer to 1.2mg/week if you are a normal responder.
hCG does not in any way convert to E2, it can promote too much E2 production in the testes for a few. Most do not have a problem.
Half life of AI and hCG do not support injecting twice a week. E2 levels will be changing. Then the lab results can be more an effect of lab timing and not representative.
Do T and hCG at the same time and your routine will be simpler to live with. The fun part of injecting can wear off.
For injections and AI twice a week, take AI at same time as T. That way the waves of anastrozole levels will somewhat match the peaks of testosterone, which is better. EOD for everything works the best in terms of simplicity and smooth T and E2 levels. Then use 0.5ml 0.5" 29 gauge insulin needles for T and hCG [not in the same syringe].
You can make these decisions on your own if you are so inclined.
