Before I started hrt I did a pct of clomid/nolv/hcg. I waited 20 weeks after that before getting bloodwork done and my test levels were still very low. If I didn't recover from that pct then I'm not going to recover. I think if you do enough cycles this is bound to happen. Not for everyone of coarse. There are those who recover better than others.
Then there are those like myself who are faced with a choice. Be on hrt for life and have low testosterone levels. It was a no brainer for me.
