Tesamorelin is a GHRH analog FDA-approved as Egrifta to reduce excess abdominal fat in adults with HIV-associated lipodystrophy. Marketing for general body-composition or anti-aging use is off-label and not supported by approval for those purposes.

Regulatory statusFDA-approved (Egrifta) for a specific indication; other uses are off-label.

What does the evidence actually show?

What human clinical evidence exists?

Approval is supported by trials in the HIV-lipodystrophy indication; general-population physique claims are not established.

What do the animal and laboratory studies show?

Preclinical GH-axis data exist. We keep animal and laboratory findings clearly separated from human evidence, because preclinical results routinely fail to translate to people.

What are the known and potential risks?

Glucose intolerance, injection-site reactions, fluid retention; off-label use carries the added uncertainty of an unstudied population.

No consumer dosing for research compoundsThis page does not provide dosing instructions for unapproved compounds, and we do not link to research-chemical sellers. If you are considering peptide therapy, do it through a licensed clinician who can weigh your individual risks.

Is it legal, and where does it come from?

The lawful pathway for any prescription peptide is a licensed clinician and a licensed pharmacy. Products labeled "for research use only" are not lawfully sold for human consumption. See how to verify a peptide provider and research peptides versus prescription therapy.

Is it banned in sport?

Prohibited under anti-doping codes.

Frequently asked questions

Is tesamorelin FDA-approved?

Yes: tesamorelin is FDA-approved as Egrifta (BLA 022505) for one use, reducing excess abdominal fat in adults with HIV-associated lipodystrophy, which makes it the only growth-hormone-releasing peptide covered on this site with an approved product on the market, as of October 15, 2026. The approval does not cover general fat loss, body recomposition or anti-ageing. On August 24, 2026 FDA sent warning letters to five online sellers of "research use only" peptides, several of which listed tesamorelin. A prescription through a licensed pharmacy is the only lawful route.

Is Tesamorelin FDA-approved?

Is there human evidence for Tesamorelin?

Approval is supported by trials in the HIV-lipodystrophy indication; general-population physique claims are not established.

Is Tesamorelin legal to buy?

Many peptides in this category are sold as 'research chemicals,' which is not a lawful pathway for human use. Legitimacy depends on approval status and whether a licensed clinician and pharmacy are involved. We do not link to research-chemical sellers.

Is Tesamorelin banned in sport?

Prohibited under anti-doping codes.

How the dates on this page work. Manufacturer self-pay prices were re-read on 15 October 2026: NovoCare’s Wegovy page and Lilly’s Zepbound savings page. Foundayo prices are carried from LillyDirect pages archived 25 September 2026, because lilly.com blocked automated reads. Figures captured from telehealth provider websites carry the date we read that provider’s page, which may be earlier; where it is, the row or a dated notice says so. We do not restamp a figure we have not re-read.
