If HIV patients stop taking the injection, the belly fat they lost comes right back quickly.

Tesamorelin only targets dangerous belly fat in HIV patients, leaving other fat stores like arms and legs unchanged.

A drug called tesamorelin helps HIV patients with belly fat buildup lose about 11% of their dangerous internal belly fat in six months, while those on a dummy pill lose almost none.

The drug doesn’t make you lose fat from your skin or your arms and legs — it only targets the fat deep inside your belly, which is the kind that’s most dangerous.

A drug called tesamorelin helps reduce belly fat deep inside the abdomen for people with HIV who are on medication, making their belly fat decrease by about 15% compared to those not taking the drug. This finding is from the abstract summary - full study details were not available

The drug only melts the fat deep inside the belly, not the fat you can pinch on the skin or in the arms and legs.
