Tesamorelin

Prompts your body's own growth hormone release. Prescribed off-label.

Tesamorelin is a growth hormone releasing hormone analog. Its commercial version, Egrifta, was FDA-approved in 2010 to reduce excess visceral abdominal fat in people with HIV-associated lipodystrophy. Prologue's tesamorelin is compounded and prescribed off-label. Compounded medications are not FDA-approved.

It prompts the pituitary to release growth hormone in its natural rhythm, which raises IGF-1. Growth hormone influences how the body stores fat, which is where the body-composition interest comes from.

Two effects need checking before your physician will prescribe it: it raises blood sugar, and it raises IGF-1.

Visceral Fat, Reduced

Randomized trials found meaningful reductions in visceral fat.

Straight Past the Gut

Daily subcutaneous injection.

Off-Label, Stated Plainly

Compounded. Active ingredient FDA-approved as Egrifta for an HIV-related condition; prescribed off-label.

What getting it involves

  1. A consultation

    A consultation with a Prologue physician.

  2. A physician reads it

    Your A1c, your fasting glucose, and your cancer history.

  3. Prescribed off-label

    Compounded. Active ingredient FDA-approved as Egrifta for an HIV-related condition; prescribed off-label.

  4. Dispensed

    Daily subcutaneous injection, compounded by a licensed pharmacy partner.

Where the evidence stands

  1. In the approved trials

    The evidence comes from randomized trials in people with HIV-associated lipodystrophy, which found meaningful reductions in visceral fat.

  2. Unknown

    No trial has been run on healthy adults taking it for body composition. The mechanism should work the same way. Whether it works as well is unknown.

The visceral fat returns when you stop taking it.

What your physician screens for

Blood sugar

Growth hormone raises glucose, and tesamorelin raises growth hormone. In Egrifta’s trials it worsened glucose control in some people. Your physician checks your A1c and fasting glucose before prescribing.

Cancer history

Growth hormone and IGF-1 are growth signals. Active malignancy is a contraindication on Egrifta’s label. Whether long-term IGF-1 elevation affects cancer risk over decades remains an open question in the literature, and your physician will weigh your family history against it.

These two risks are specific to tesamorelin. The consultation also covers your full medical history, and your physician may ask for recent lab results depending on what they find.

How it's prescribed

Daily subcutaneous injection.

There's no established dose for the off-label use. Your physician sets it against your lab results, including IGF-1, and adjusts.

Compounded by a licensed pharmacy partner and tested for potency, sterility, and endotoxin levels before shipment.

Questions

Nothing is charged when you join. Billing begins only after a physician has approved your plan. If they decide treatment isn't appropriate for you, you are not charged.
It is gentler than most people expect. The needle is the size of an insulin pen — thin and short, designed for subcutaneous tissue rather than muscle. Your physician can walk you through the technique at your consultation, and most patients are comfortable with the routine by the end of the first week.
Tesamorelin is compounded by a licensed pharmacy partner and ships with everything you need: vials, syringes, alcohol swabs, and sharps disposal.
It's a subcutaneous injection, given at home. Your physician sets the schedule, so the frequency is decided for you rather than fixed in advance.
The first dose takes about a minute. Your physician can walk you through the technique at your consultation, and you'll have everything you need in the first shipment.
Tell your physician at your intake. The needle is short and fine, and most people settle into the routine within the first couple of weeks — but if self-injection isn't workable for you, say so and your physician will talk through the alternatives.
For anything urgent, call 911 or your primary care physician — Prologue is not an emergency service. For everything else, write to the care team. Clinical questions get a reply within 24 hours.
Standard shipping for oral medications. Cold-chain shipping for injectables.
Protocol adjustments happen as your response shows up. If the dose or cadence changes, your next shipment reflects the change. There is no additional fee for protocol adjustments within your existing protocol.
Refills go out on the cadence your physician sets, without you having to ask.
