What is Tesamorelin used for?

Tesamorelin is a synthetic peptide that acts as a growth hormone-releasing hormone (GHRH) analog. It is primarily investigated for its potential to reduce visceral fat in individuals with HIV-associated lipodystrophy, a condition characterized by abnormal fat distribution often exacerbated by antiretroviral therapy. Tesamorelin stimulates the release of endogenous growth hormone, which in turn promotes lipolysis and reduces visceral adipose tissue (VAT) accumulation.

What people are saying

anecdotal · not evidence

Unverified first-hand accounts from public forums. These are not studies: nobody checked what was taken, whether it was what the label said, or what else was going on. They count for nothing in the evidence grade above and are shown because a reader searching Tesamorelin will meet them anyway, and meeting them next to a graded evidence base is better than meeting them alone.

Community collection has not run yet, so this is an empty shelf rather than a quiet one — nothing has been read, and no conclusion about how much Tesamorelin is discussed should be drawn from it.
