EVIDENCE TAKEAWAY

The short answer.

Tesamorelin has the strongest human evidence in a narrow, labeled population. Evidence from that population should not be generalized to routine weight management.

WHAT IS TESAMORELIN?

Start with identity.

A growth hormone-releasing hormone analog with an FDA-approved use for a specific HIV-associated lipodystrophy population.

HUMAN VS PRECLINICAL

What evidence exists for Tesamorelin?

HUMAN EVIDENCE
5/5 · Approved indication

Multiple randomized trials support one specific FDA-approved indication in adults with HIV and lipodystrophy.

PRECLINICAL EVIDENCE
3/5 · Mechanism supported

Growth-hormone-releasing activity is well characterized, but approved-use evidence is human and indication-specific.

RESEARCH INTENT

U.S. REGULATORY STATUS

Is Tesamorelin FDA approved?

FDA approved only to reduce excess abdominal fat in HIV-infected adults with lipodystrophy; not indicated for weight-loss management.

SPORT STATUS

Is Tesamorelin prohibited in sport?

Prohibited at all times under the 2026 WADA List (S2).

3 sources Evidence limits

What are the main evidence limits for Tesamorelin?

Approval is product-, indication-, and population-specific. It does not validate every compounded formulation or off-label claim.

3 sources Decision question

What is currently being studied for visceral fat?

The evidence depends on the population and the question. An approved indication, obesity treatment, and investigational research should not be collapsed into one list.
