I got a name, for what I thought was going to be a local source, turned out it was a guy who was fucking huge and recommended me his TRT doc

He said that a T level of 800-1000 was good, I thought normal range was 400ish-1000ish naturally. Wouldn't you want it closer to 1200-1500?
He said clomid can shut you down (I thought it was supposed to help get your levels back to normal during PCT) and recommended Nolvadex instead. But I thought Nolvadex was an AI.

Recap:
-Do people not go to TRT doc for scripts for cycles?
-What should T levels be during a cycle?
-Does clomid actually shut you down?

Could someone please clear up some of my confusion
