Great response to a SERM. I am happy for you. Looks like you may not need a lifetime of injections. I would do a restart like this once or twice a year if I was you. I am even thinking of doing a Nolva restart myself and see how I respond.
Now, I would reccomend you do another E2 test, especially if you do not feel any low E2 sides. With that low of a Adex dose, it might be a lab error. I've used privatemdlabs before and found it to be unreliable due to LabCorp. I am using labsmd.com, a sister company that uses Quest for testing. Prices are identical without the 15% discount, however. I've found Quest to be much more reliable than LabCorp.
My blood drawn on the same day:
LabCorp: E2: <5, range 7-42
Quest: E2: 32, range <39
I had no low E2 sides. Just something to think about.
