If you want to run 500mg per week then start there. It takes 5-6 weeks for the test to fully saturate your blood.
Add in the anavar later in the cycle when lifts stall.
Basically what @s.gentz stated. Keep an AI handy at that dose as you may need a bit but use it sparingly. For example I use .125mg compounded of Arimadex per week. A little goes a long way.
No you don’t but you run the risk of letting estrogen out of control.
Nolva is a serm. It blocks estrogen at breast receptor sites. Does not block estrogen conversion nor lower it in your blood.
This is personal. We are all different. Some guys can run 800 mg/wk test with no issues. Some have issues on 100mg/wk. only way to know is by bloodwork or with more experience by feel.
Going against the norm here. Have you tried training in/with different modalities before heading into PED’s? I firmly believe it’s achievable to reach a much higher muscular bodyweight with similar bodyweight percentage - as a natural. How’s your strength numbers in the big 3 lifts? What does “trained hard” mean? Your numbers after 15 years (!) of training indicate you’re more of a metcon athlete.
@s.gentz beat me to it with a very through and sound response as always. If your only side effect is nipple tenderness / lump then Nolva is fine. If you’re getting erectile, emotional or excess bloating then an AI is likely better.
