If HIV patients stop taking tesamorelin and switch to a dummy pill, their dangerous belly fat quickly returns to previous levels.

Scientific Claim

Switching from tesamorelin to placebo reverses the reduction in visceral adipose tissue in HIV-infected patients with central fat accumulation.

Original Statement

“The initial improvements over 6 months in VAT were rapidly lost in those switching from tesamorelin to placebo.”
