Thats quite a situation to be in. I would be interested to know your age. If you are 25, then I would think hard about this. It may be worth trying to come off and recover. If you are 40, then you might want to just stay on HRT, as this is a normal age for it anyway.
If you want to stay on, get your labs done so you can dial in your test levels and know how much you need to maintain normal levels. Also you want to be sure that you are not causing harm to your organs. If you do want to try coming off, I would blast some HCG first. While on your test replacement dose, I'd start HCG at 500 iu, every 3 days for 2 wks. Then after 2 wks of this therapy, start Clomid at 50mg ED, along with the HCG and stop the test. At this time, stop the test. Then after 2 more weeks, stop the HCG and continue on Clomid at 50mg for at least 4-6 wks. At that point, you can try to come off the Clomid and see if you have recovered. If you feel like you are crashing at that point. Remeat the clomid and HCG therapy without taking test
