Benefits

What tesamorelin may do for you

target

Studied for visceral fat

In clinical trials for its approved use, tesamorelin reduced visceral fat, the deep fat around the abdominal organs.

neurology

Works with your own system

Stimulates the pituitary to release your own growth hormone rather than supplying it directly.

Body composition focus

Providers may consider it off-label when abdominal and visceral fat are a specific concern.

lab_profile

Monitored with labs

Your provider monitors growth-hormone markers (IGF-1) and blood sugar during treatment.

Evidence outside the FDA-approved use is limited, and individual results vary. Your provider will review the risks, benefits, and alternatives with you.

How it works

The science, simply.

Tesamorelin is a stabilized version of growth-hormone–releasing factor, the brain signal that tells the pituitary gland to release growth hormone.

The resulting rise in growth hormone and IGF-1 affects how the body stores and uses fat, particularly visceral fat around the abdomen.

Acts on the pituitary's GHRH receptor

FDA status

Tesamorelin is FDA-approved to reduce excess abdominal fat in adults with HIV and lipodystrophy. Use for any other purpose, including general weight or body-composition goals, is off-label. If your prescription is compounded, the compounded medication is not FDA-approved. Prescription treatments require a medical evaluation by a licensed provider, who decides whether a treatment is appropriate for you. Not everyone qualifies. See Important Safety Information.

FAQ

Questions about tesamorelin

Is tesamorelin a weight-loss drug?

Its FDA-approved use is reducing excess abdominal fat in adults with HIV-associated lipodystrophy. Any other use is off-label, and your provider will review whether it's appropriate for you.

How is it different from sermorelin?

Both prompt the body to release its own growth hormone. Tesamorelin has an FDA-approved indication and is studied specifically for visceral fat; sermorelin is generally used for recovery and body-composition goals.

When is it taken?

Once a day, as an injection under the skin of the abdomen, at the dose your provider prescribes.

Does it affect blood sugar?

It can raise blood sugar in some people, so your provider monitors it, especially if you have diabetes or prediabetes.
