Chorionic gonadotropin and menopausal gonadotropin.
If there is no result with hCG, then we already know that after such a long therapy it will be difficult to do something, but it is possible. Here I will advise you to read Dr. Michael Scally and his protocols.

I apologize for the typo in the name. Elevated prolactin is fraught with problems with libido (for example) in the same way as highly elevated estradiol. If prolactin is elevated, then try cabergoline. Regarding the degree of prolactin overestimation, choose the starting dosage and that's it: either 1/2 tablet once a week for a couple of weeks and / or 1/4 every ten days. Libido will jump and the feeling of motivation too. If you drop it hard, it can weaken the immune system.
From vitamins, you can take at least Optimen from Optimum Nutrition (not advertising, but the complex is good). Clomid in order to raise your testosterone. You can sit on it for a long time and cancel without consequences. Sometimes it is worth monitoring estradiol for symptoms.
