lolllllll
go down like two or three posts and you can see people discussing (and then arguing) about the same topic, replete with personal attacks on others' IQ and academic training for having differing viewpoints, even!
Nobody can tell you the answer to your question.
Everybody is different. Some need an AI on TRT and some don't. Some actually need more estrogen even when they are at high normal test levels from injections.
Some feel better on HCG, some feel worse. Some have their fertility restarted with HCG, some don't. Some even keep their fertility for years into cycling without using HCG ever. Some lose it after one cycle.
The best bet if you want to stabilize on TRT is to start on 70-100mg testosterone/week with no ancillary drugs and get bloodwork after about 6-8 weeks in. Then assess with a well-trained physician.
