False testosterone reading?

Yes, I have dealt with low-t levels for several years now. I was on therapy for it for many of them. But, then my provider stopped covering it, I also have hypothyroidism, which I take levothyroxine for, and a micro-adenoma on my pituitary gland that has remained at the same size since I was first diagnosed as having it, although it’s been a few years since my last MRI. Anyway, the last two times my t levels were tested they came back at being 50 percent higher than all previous results. But, the thing is I have had no change in my energy levels and can’t gain any muscle mass. The last time my levels were this higher prior to these last two readings was when I was on testosterone therapy, during which time I had far more energy and could actually gain a little muscle mass. But, since I can’t now, despite the much higher readings of my last 2 testosterone tests, could it be something is causing a false reading to turn up? But, if not, then why do I feel just as tired as I did before, and can’t gain any muscle mass no matter how much I exercise?
