For just TRT you should be taking only 100 to 150 mg of Testosterone Cypionate split into two doses a week. Then also you need to take Gonadorelin 2X a week subcutaneously and that should keep your marbles at a normal size. As long as you are not excessively high in Body fat you will not need an AI, but still have one on hand. If your BF is high you will most likely need the AI as body fat aids in transferring testosterone to estrogen. This is the reason people should stay away from Tren, dbol, Deca, and such until they get their body fat low enough.
You will also need to get blood tests every 5-6 weeks till you get two blood tests that are pretty much equal and show that you have obtained healthy levels of test and estrogen at normalized levels, then you can start testing 1 to 2 times a year.
