Your protocol

How Tesamorelin is prescribed.

Who it's for
  • Adults with stubborn visceral (abdominal) fat
  • Patients pursuing body recomposition under physician supervision
  • People who want the strongest growth-hormone release this class of peptide offers

Your physician decides whether Tesamorelin is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.25 mL (25 units) subcutaneously Monday through Friday nights at bedtime.

Cycle. Nightly, Monday through Friday, on an empty stomach. Ongoing monthly treatment; your physician adjusts the dose over time.
Ready for more? When you're ready for more, ask your physician to move you up to the next strength. Approved steps are charged at the price difference and applied to your next fill.
Directions shown are the pharmacy's standard for this preparation. Your prescription label is the final word.
What's included
  • Licensed physician review of your intake, history, and labs
  • Medication compounded to your prescription by a PCAB-accredited, FDA-registered pharmacy
  • Every batch independently tested before release
  • Sterile syringes and alcohol prep pads for injectables
  • Tracked delivery to your door, refills on schedule
  • Message your physician anytime; dose changes without an appointment
Storage & handling
  • Store refrigerated (36–46°F / 2–8°C) at all times, including before first use.
  • One vial is your monthly supply. A fresh vial ships every 28 days on your refill schedule, so you're always well inside the beyond-use date on your label.
  • Protect from light. Wipe the stopper with an alcohol pad before every draw.
  • Dispose of syringes in the sharps container per the included instructions.
What to expect

A typical course of Tesamorelin.

TimeframeWhat patients commonly report
Weeks 1–3Many patients first notice deeper sleep, better recovery, and more daytime energy.
Weeks 4–8Changes around the midsection often become noticeable, especially with training and adequate protein. In its FDA trials tesamorelin reduced visceral fat over this timeframe.
Weeks 9–15 and onEffects tend to be cumulative and build with continued use. Your physician adjusts the dose over time.
Individual results vary. Compounded medications are not FDA-approved; a licensed physician determines whether treatment is appropriate and monitors your progress.

The science

How Tesamorelin works, and what the research shows.

How it works

Tesamorelin is a GHRH analog FDA-studied specifically for visceral fat reduction.

It's the only growth hormone releasing peptide with clinical trial data showing significant reduction in dangerous abdominal fat.

Clinical evidence
  • Tesamorelin has the strongest human evidence of any GHRH analog: it is FDA-approved (Egrifta) for excess abdominal fat in HIV-associated lipodystrophy, where phase 3 trials showed roughly 15–18% reductions in visceral adipose tissue over 26 weeks.

    Falutz et al., N Engl J Med 2007; and subsequent randomized trials
  • Use outside that indication — including general body-composition protocols — is off-label and decided by the prescribing physician.
