Tesamorelin: evidence, legality and safety

Quick answer

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 the evidence shows

Human clinical evidence

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

Animal and laboratory evidence

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.

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.

Legality and sourcing

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.

Status in sport

Prohibited under anti-doping codes.

Frequently asked questions

Is Tesamorelin FDA-approved?

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

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.
