People with HIV and belly fat who responded to tesamorelin had 0.64 to 1.08 square centimeters more lean muscle in their trunk muscles compared to those who didn't take the drug.

HIV patients with belly fat who responded to tesamorelin had more lean muscle mass in all four trunk muscles, with increases between 0.64 and 1.08 cm² compared to placebo after 26 weeks.

This drug didn’t just make muscles less fatty—it also made them bigger in size, adding about half a square inch of lean muscle in the core area after six months.

Even after accounting for belly fat loss, tesamorelin still increased lean muscle in people with HIV and belly fat, suggesting other factors are involved.

For HIV patients with belly fat who responded to tesamorelin, the drug was linked to better muscle density in four trunk muscles, with improvements between 1.56 and 4.86 units compared to placebo after 26 weeks.

For people with HIV and belly fat who responded to tesamorelin, the drug helped increase muscle density in their trunk muscles by 1.56 to 4.86 units compared to those who didn't take it.
