The injection makes the waist smaller relative to the hips, giving a less 'apple-shaped' body and more 'pear-shaped' proportions.

Scientific Claim

Tesamorelin (2 mg subcutaneous daily) reduces waist-hip ratio by a statistically significant amount in HIV-infected adults on antiretroviral therapy with abdominal fat accumulation over 6 months, indicating improved body fat distribution.

Original Statement

“Trunk fat (P < 0.001), waist circumference (P = 0.02), and waist-hip-ratio (P = 0.001) improved, with no change in limb or abdominal SC fat.”

This study found that a daily shot of tesamorelin helped HIV patients with belly fat lose fat around their waist and improve their waist-to-hip shape, and it worked better than a placebo.

Similar Assertions

People who took the drug ended up with a smaller waist compared to their hips — a sign their body fat shifted from the belly to less dangerous areas.

97%

Doctors who didn’t know who got the real drug thought patients’ bellies looked better after treatment.

90%

The drug shrinks the fat around the torso and makes the waist smaller, but doesn’t change the fat on the arms, legs, or just under the skin — meaning it targets only the dangerous internal fat.

90%

This injection makes the waist smaller without changing fat on the arms, legs, or just under the skin.

90%

If HIV patients keep taking the injection for a full year, they lose even more belly fat inside their abdomen—about 18% total.
