Based on the information you've provided, I say that it is likely that if you stop using the tamoxifen and continue the testosterone replacement therapy (TRT) your condition will reoccur.
From what you've stated, you have likely accomplished two things that have contributed to the elimination of your gyno. First, using the Adex, you drove your estrogen levels down significantly. Over time, that would have by itself provided you some relief. Additionally, by using the tamoxifen after you discontinued the Adex, you introduced a competitive binding option at the estrogen receptors in your breast tissue that were previously available for estrogen binding. The tamoxifen has a higher binding affinity to the estrogen receptor and is now binding in place of any estrogen to the previously affected receptors.
I would not stop using the tamoifen while you are still taking the test. At 120 mgs per week, you obviously hae a very strong inclination for aromitazation and to discontinue the tamoxifen while still using thetest would open up the receptors to estrogen binding again.
If you want to stop using the tamoxifen, reduce your test levels first. I'd suggest you get a blood test to see where you are in terms of test levels now. You will need to lower than where you are now in terms of test levels to mitigate the problem from occurring in the future. Once you get your test levels down, make sure your estrogen levels are also in a normal or acceptable range before you remove the tamoxifen.
How many mgs per day of tamoxifen are you currently using? 10 - 20 mgs a day should be all you need and you can use that dosage for an extend time fame but I would suggest that you use as little tamoxifen as possible to manage the issue since it does have some hepatic impact
