What is Tesamorelin?

Tesamorelin is a synthetic GHRH analog that is currently FDA-approved (brand name Egrifta) for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. It is one of the few peptides in this space with full FDA approval for a therapeutic indication, which provides a stronger evidence base than most other peptides discussed for body composition.

Preliminary

How It Works

Tesamorelin works the same way as your body's natural growth hormone-releasing hormone, but with modifications that make it more potent and longer-lasting. It tells your pituitary gland to release more growth hormone, which in turn helps reduce visceral (deep belly) fat.

Common Side Effects

Injection site reactionsJoint painPeripheral edemaParesthesia

Cautions

  • FDA-approved only for HIV lipodystrophy
  • Contraindicated in pregnancy
  • Monitor IGF-1 levels
