Key points

  • The only FDA-approved compound in the growth-hormone group (brand Egrifta).
  • Approved to reduce excess visceral (deep abdominal) fat in people with HIV lipodystrophy.
  • Strongest evidence base of the GH peptides - real controlled trials.
  • Prescription-only; benefits reverse when stopped.

Overview

Tesamorelin is a stabilized synthetic GHRH analog and the standout of the growth-hormone group because it is a genuine, FDA-approved drug (Egrifta / Egrifta SV / Egrifta WR). It's approved specifically to reduce the excess deep-belly (visceral) fat that can accumulate in people with HIV.

Because it's approved, it has been through the controlled trials most peptides here lack, which makes its evidence far stronger.

How it works

It stimulates the pituitary to release the body's own growth hormone; the resulting GH/IGF-1 rise is lipolytic and preferentially mobilizes metabolically active visceral fat while largely sparing fat just under the skin.

What the research shows

Randomized trials and meta-analyses show roughly a 15-18% reduction in visceral fat versus placebo, along with improvements in trunk fat, liver fat, waist circumference and lipids. Most adverse events in trials were mild. It's also studied for fatty-liver disease (NAFLD).

Benefits

FDA-approved and evidence-backed, with targeted, well-documented visceral-fat reduction - the 'legitimate, studied' option in this group.

Metabolic improvements (lipids, liver fat) accompany the fat loss.

Risks & side effects

Common effects include joint pain, injection-site reactions, limb pain, swelling and muscle aches; it can raise IGF-1 and affect blood sugar/insulin sensitivity.

It requires daily injection, is expensive, benefits reverse on stopping, and it's contraindicated in active cancer and pregnancy.

Practical considerations

A prescription drug used under medical supervision for its labeled HIV-lipodystrophy indication; newer formulations reduce the reconstitution burden. Unlike the others in this group, it is a finished, approved product.

Frequently asked questions

Is tesamorelin FDA-approved?
Yes - as Egrifta (and Egrifta SV/WR), to reduce excess visceral abdominal fat in people with HIV-associated lipodystrophy.
What does it actually do?
It boosts your own growth hormone, which preferentially burns deep visceral belly fat - about 15-18% reduction versus placebo in trials.
Is it used for general weight loss?
Its approval is specific to HIV-related visceral fat. Broader use is off-label, and it targets visceral (not subcutaneous) fat.
What are the side effects?
Joint and limb pain, injection-site reactions, swelling, and effects on IGF-1 and blood sugar; contraindicated in active cancer and pregnancy.
Do results last after stopping?
No - the visceral fat tends to return once treatment stops.
