Weight-loss drug found to shrink muscle in mice, human cells

It's my understanding that if you have hypertension, your heart muscle grows thicker as a consequence of working harder against your blood pressure, which reduces the flow capacity of your heart.

So if you have hypertension, this might actually be a "good" side-effect?

I was also thinking if in used with testestrone, which is dangerous because the heart is a muscle and unintended consequence of trt is heart muscle growth which decreases blood flow.
