FDA Approved (Egrifta)What is Tesamorelin?
Tesamorelin is a modified version of GHRH (Growth Hormone Releasing Hormone) that received FDA approval in 2010 under the brand name Egrifta. It was approved specifically for reducing visceral adipose tissue in HIV patients with lipodystrophy. That's a narrow indication, but the mechanism works for anyone with excess visceral fat. Browse the full peptide library for related GH compounds.
What makes tesamorelin unique is the clinical data. This isn't a peptide where we're extrapolating from rat studies or relying on anecdotes. Phase 3 clinical trials showed 15 to 26 percent reductions in visceral fat over 26 weeks. That's the fat surrounding your organs, the metabolically dangerous stuff linked to heart disease, insulin resistance, and chronic inflammation. For GLP-1-based weight loss instead, see the weight loss hub.
Most growth hormone peptides get used off-label for body composition. Tesamorelin is the exception. It has actual FDA approval, actual clinical trial data, and a specific indication for fat reduction. It pairs well with the CJC-1295/Ipamorelin stack for overall body composition. For expats in Vietnam looking to address stubborn belly fat through peptides, this is often where the conversation starts.
How It Works
Visceral Fat Targets: Not all body fat is equal. Subcutaneous fat, the stuff you can pinch, is relatively harmless. Visceral fat is different. It wraps around your liver, pancreas, and intestines. It actively secretes inflammatory compounds. It drives insulin resistance. You can be relatively lean everywhere else and still carry dangerous amounts of visceral fat.
GHRH Binding: Tesamorelin binds to GHRH receptors in your pituitary gland, triggering growth hormone release. Unlike synthetic HGH which delivers a constant dose, tesamorelin works with your body's natural pulsatile GH secretion. This is generally considered safer and more physiological.
Lipolysis Mechanism: The elevated GH then drives IGF-1 production in your liver. IGF-1 promotes lipolysis, the breakdown of stored fat into usable energy. The combination of elevated GH and IGF-1 creates a metabolic environment that favors fat loss, particularly from visceral stores.
Benefits
- 15–26% reduction in visceral adipose tissue (proven in clinical trials)
- FDA-approved with extensive safety and efficacy data
- Improved lipid profiles and insulin sensitivity
- Natural pulsatile GH release patterns (safer than synthetic HGH)
- Once-daily dosing for convenience and compliance
- Anti-inflammatory and cardiovascular benefits from visceral fat reduction
Dosing Protocol
| Phase | Dose | Frequency | Duration |
|---|---|---|---|
| Weeks 1–4 | 1mg daily | Subcutaneous injection | Assessment phase |
| Weeks 5–26 | 2mg daily | Subcutaneous injection | Maximum fat reduction |
| Ongoing | 1–2mg daily | Subcutaneous injection | Maintenance or cycles |
Always start at the lowest effective dose and titrate up gradually.
Side Effects
Common
- ⚠Injection site reactions (redness, itching, swelling): usually mild and temporary
- ⚠Fluid retention and edema, especially in first weeks: hands, feet, face may feel puffy
- ⚠Joint pain (arthralgia) from elevated GH: wrists, fingers, knees common
- ⚠Tingling or numbness in hands from fluid retention compressing nerves
- ⚠Elevated blood glucose: monitor if diabetic or prediabetic
Rare
- •Pituitary dysfunction with very long-term use: theoretical concern
- •Significant hyperglycemia in predisposed individuals: discontinue if blood sugar becomes difficult to control
Who Should NOT Use Tesamorelin
- ✕Active malignancy or history of cancer: GH and IGF-1 can promote tumor growth
- ✕Hypersensitivity to GHRH or tesamorelin: allergic reactions possible
- ✕Pregnancy: fetal risk in animal studies
- ✕Disruption of the hypothalamic-pituitary axis from surgery, trauma, or radiation
- ✕Uncontrolled diabetes: GH effects on blood sugar make management difficult
What to Expect
Initial water retention is common as GH levels rise. You might feel puffy or notice tighter rings and shoes. Minor injection site reactions like redness or itching happen occasionally. Some people notice better sleep quality from the first week.
Water retention typically normalizes. Waist measurements start decreasing even if scale weight stays similar. Energy and recovery often improve. Skin quality may improve.
This is the clinical trial sweet spot. Most significant visceral fat reductions happen in this window. Body composition shifts become visible. Pants fit differently. The midsection leans out.
Visceral fat reduction plateaus but maintains as long as you continue. Some people cycle off to assess if lifestyle changes can maintain results. Others continue indefinitely at maintenance doses.
Notes from Ho Chi Minh City
Tesamorelin is the GH peptide I would actually pick over the CJC plus Ipamorelin stack if visceral fat is the specific problem rather than general body composition, because the FDA approval for HIV-associated lipodystrophy was earned on visceral fat reduction specifically. The Thao Dien expat demographic carrying 5 to 10kg of belly fat from the post-relocation dietary shift toward banh mi at the An Phu deli stalls and Saturday-night Pasteur Street beer rotations responds well to a 2mg daily subcutaneous protocol, and the visible waist circumference change at week 12 is one of the cleanest peptide effects you can measure with just a tape. I baselined waist at the navel and visceral fat percentage on the InBody scan at California Fitness in Crescent Mall before starting, then re-tested at week 8 and week 16; the waist drop was 7cm and the visceral score moved from 11 down to 7 with no change to my BJJ training schedule at Saigon Sports Club. Egrifta brand is not available in Vietnam, only research-grade vials through cold-chain importers at 2 to 3.5 million VND per 10mg vial.
Sourcing in Vietnam
Branded Egrifta tesamorelin is not distributed in Vietnam and is not stocked at Long Châu, Pharmacity, Vinmec, or FV Hospital. Sourcing is research-grade only through cold-chain importers (2 to 3.5 million VND per 10mg vial). See the supplier list and COA guide before purchasing.
FAQ
Q: Is tesamorelin better than CJC-1295 for fat loss?
A: For specifically targeting visceral fat, tesamorelin has the best clinical data. For overall body composition including muscle gain on a budget, the CJC-1295/Ipamorelin stack is more versatile. Tesamorelin costs roughly three times more. If visceral fat is your primary concern and budget allows, tesamorelin is the stronger choice.
Q: Can I use tesamorelin and ipamorelin together?
A: Yes. Tesamorelin works through GHRH receptors. Ipamorelin works through GHSR receptors. Combining them stimulates GH release through complementary pathways. This is a valid stack similar to CJC-1295/ipamorelin but with tesamorelin's visceral fat data.
Q: How long until I see results from tesamorelin?
A: Most users notice changes in waist measurements by weeks 4 to 6. Maximum visceral fat reduction occurs over 3 to 6 months based on clinical trial data. This is not a quick fix.
Q: Does visceral fat return when I stop tesamorelin?
A: Generally yes, fat tends to return after discontinuation. This is why many users continue long-term at maintenance doses or implement strict diet and exercise during the protocol to maintain results afterward.
Q: Where can I buy tesamorelin in Vietnam?
A: Research grade tesamorelin is available through peptide suppliers shipping to Vietnam. Branded Egrifta is not distributed here. Check the community-verified supplier list with COA verification and cold chain shipping.
Q: What's the difference between tesamorelin and HGH?
A: Tesamorelin stimulates your pituitary to release its own growth hormone. HGH is synthetic growth hormone injected directly. Tesamorelin maintains natural pulsatile release patterns and is generally considered safer for long-term use. HGH is more potent but carries more risks with chronic use.
