Tesamorelin Injection
The FDA-Approved GHRH Analog
Create an account to view pricing and personalized plans.
Get StartedTesamorelin is a growth hormone-releasing hormone (GHRH) analog that stimulates your pituitary gland to produce growth hormone naturally. It is the only peptide in its class with FDA approval (for HIV-associated lipodystrophy) and has been studied in multiple Phase III trials for its ability to reduce visceral fat.
Tesamorelin may support targeted visceral fat reduction, improved body composition, better lipid profiles, increased energy, and enhanced metabolic function. It preserves lean muscle mass while reducing the deep abdominal fat that wraps around your organs.
Tesamorelin is administered as a simple subcutaneous injection. Typical dosing includes one injection per day on a provider-determined schedule. PeRx ships it fully reconstituted and ready to use. Insulin syringes and a step-by-step guide are included.

Lose the visceral fat that won't respond to anything else.
Visceral fat is the deep abdominal fat that wraps around your organs. It drives metabolic disease, insulin resistance, and cardiovascular risk. And it barely responds to diet and exercise once it sets in.
Tesamorelin is the only growth hormone-releasing peptide with FDA approval. In Phase III clinical trials, it reduced visceral fat by 15% in 26 weeks while preserving lean muscle mass. It works by telling your pituitary gland to produce more of the growth hormone your body already makes, just at the levels it used to.
Why do people explore Tesamorelin therapy?
May reduce visceral fat by up to 15% while preserving lean muscle mass and strength.
May improve body composition by shifting the balance from fat storage to fat burning.
May boost energy and endurance by restoring growth hormone to more youthful levels.
May improve sleep quality through optimized growth hormone release during nighttime cycles.
May support healthier lipid profiles and triglyceride levels, improving overall metabolic markers.

Tesamorelin vs. CJC-1295/Ipamorelin
Both target growth hormone. Here's how they differ.
Tesamorelin
FDA-approved GHRH
| Tesamorelin | CJC-1295/Ipamorelin | |
|---|---|---|
| Best For | Visceral fat reduction, metabolic optimization | Broad GH support: body comp, sleep, recovery |
| How It Works | Stimulates GH release via GHRH pathway | Dual-pathway GH release (GHRH + Ghrelin) |
| FDA Status | FDA-approved for lipodystrophy | Compounded: no FDA approval |
| Ideal If You Have | Stubborn abdominal fat, metabolic concerns | Multiple goals: fat loss, muscle, sleep, anti-aging |
| Can Combine? | Yes — pairs well with Ipamorelin | Yes — pairs well with Sermorelin |

My midsection finally changed
“I train five days a week and eat clean but the belly fat would not budge. Three months on Tesamorelin and my waist is down two inches. Nothing else worked like this.”
Greg P.
Tesamorelin
Better energy and body comp at 52
“My doctor ran labs and my GH was tanked. Started Tesamorelin through PeRx and within six weeks I had more energy, better sleep, and my clothes fit again. Wish I started sooner.”
Lisa M.
Tesamorelin
Legit medical process, real results
“Was nervous about online peptide therapy but PeRx made it feel like a real doctor visit. Provider reviewed my screening, medication arrived overnight. Visceral fat is finally coming down.”
Ryan K.
Tesamorelin
The only thing that moved the scale
“Menopause hit my metabolism hard. Diet and exercise stopped working for the midsection. Tesamorelin is the first thing that actually changed my body composition in three years.”
Angela W.
Tesamorelin
Sleep improved before the fat loss did
“Unexpected bonus: my sleep got dramatically better in the first two weeks. The fat reduction followed by month two. Both are reasons enough to stay on it.”

Tesamorelin Injection
Tesamorelin is a synthetic growth hormone-releasing hormone (GHRH) analog. It stimulates your pituitary gland to produce growth hormone naturally. It is the only peptide in its class with FDA approval for the reduction of visceral fat (specifically in HIV-associated lipodystrophy).
The most commonly reported side effects are mild: injection site reactions (redness, soreness), joint pain, and mild swelling. Some people experience temporary tingling or numbness in their hands during the first few weeks, which typically resolves. Multiple FDA-reviewed clinical trials have established its safety profile.
Tesamorelin is not recommended if you are pregnant or breastfeeding, have active malignancy, have a history of pituitary conditions, or are hypersensitive to any component. Always disclose your full medical history during screening.
Most patients notice subtle energy and sleep improvements within 1-2 weeks. Measurable changes in body composition typically begin by weeks 3-6, with significant visceral fat reduction by weeks 6-12. Full protocols usually run 12+ weeks.
PeRx ships Tesamorelin fully reconstituted and ready to use. Store refrigerated at 36-46°F (2-8°C). Do not freeze. Keep the vial upright and away from direct light.
Yes. Tesamorelin (brand name Egrifta) is FDA-approved for the reduction of excess abdominal fat in HIV-infected patients with lipodystrophy. Off-label use for general visceral fat reduction is prescribed by licensed providers and compounded at FDA-registered 503A pharmacies.
No. The entire process is done online. Complete a health screening, a licensed provider reviews your profile remotely, and your medication ships directly to your door via FedEx Overnight.
Every order includes a provider evaluation and prescription, pharmacy-grade Tesamorelin from an FDA-registered 503A pharmacy, insulin syringes, alcohol swabs, a step-by-step injection guide, and FedEx Overnight shipping.
Yes. Tesamorelin pairs well with Ipamorelin (dual-pathway GH optimization), MOTS-C (metabolic synergy), and Sermorelin (complementary GH support). Your provider can advise on combinations.
Tesamorelin stimulates your pituitary gland to produce its own growth hormone naturally. Synthetic HGH injects growth hormone directly, which can suppress your body’s own production and carries greater risk of side effects. Tesamorelin works with your body, not instead of it.
