It sucks to hear you are having to deal with this. Having an adenoma really won't give any symptoms until its quite large ~5cm and at that point, a rupture could kill you. If mine wasn't growing so aggressively (doubled in size in two years) and if the biopsy didn't come back as beta catenin mutated (most likely to become cancer), I might have just stayed on TRT dosages only and seen if it would decrease in size.
When adenomas appear in women from birth control, they often disappear once the estrogen based BC is stopped. This hasn't been shown in men, probably because adenomas are very rare in men and seemingly almost always caused by AAS usage, specifically 17AA oral steroids (and maybe tren or nandrolone).
You are lucky yours showed up on ultrasound, mine would not show up on ultrasound and only were visible on MRI with special contrasts. Did the ultrasound measure how big the possible adenoma is? If your MRI shows that it is likely an adenoma (at least not a benign hyperplasia) then you may have to do a nuclear CT scan to rule out hemangioma before you can biopsy it (can't biopsy a hemangioma, it will just bleed). If it is still really small then you may just want to monitor it and see if it grows before going for a biopsy.
