Tesamorelin
approvedGHRH analog for visceral fat reduction and growth hormone stimulation
Availability in Thailand
Tesamorelin is available from Thai peptide vendors and select anti-aging clinics in Bangkok. It is one of the few GH-related peptides with formal regulatory approval (for HIV-associated lipodystrophy), though it is typically used off-label for visceral fat reduction and anti-aging.
Prescription: Not required from peptide vendors in Thailand.
Legal status: Has regulatory approval in some countries for HIV lipodystrophy. Available as a research peptide in Thailand.
Where to Buy in Thailand
Tesamorelin pricing varies by vendor. Often more expensive than CJC-1295 due to higher daily dosing requirements. Check vendor websites for current rates.

Overview
Tesamorelin is a synthetic 44-amino acid analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce and release natural growth hormone. It is one of the few GH-related peptides with formal regulatory approval — approved for reducing visceral abdominal fat in HIV-associated lipodystrophy. Its ability to specifically target visceral fat while stimulating natural GH production has made it popular beyond its approved indication.
How It Works
GHRH receptor stimulation
Tesamorelin binds to GHRH receptors on pituitary somatotroph cells, stimulating the synthesis and pulsatile release of endogenous growth hormone. The trans-3-hexenoic acid modification improves stability over native GHRH.
Visceral fat targeting
Clinical trials demonstrated specific reduction in visceral adipose tissue (the dangerous fat surrounding organs) with tesamorelin. This effect appears driven by GH-mediated lipolysis concentrated in visceral fat stores, which are more responsive to GH than subcutaneous fat.
IGF-1 elevation
By stimulating natural GH production, tesamorelin downstream increases IGF-1 levels. This supports muscle maintenance, cellular repair, and metabolic health — without the risks of exogenous GH injection.
Protocol Quick Reference
Benefits & Uses
- Visceral fat reduction: Clinical trials showed significant reduction in visceral abdominal fat, the metabolically dangerous fat surrounding organs
- Liver fat reduction: Research demonstrated reduced hepatic steatosis (liver fat) — relevant for metabolic health
- Natural GH stimulation: Raises GH and IGF-1 through the body's own production pathways, not exogenous injection
- Body composition improvement: Supports lean mass preservation while reducing fat, particularly in the abdominal area
- Regulatory approval history: One of the few GH-related peptides with formal approval — stronger safety evidence than most research peptides
- Anti-aging effects: GH and IGF-1 elevation supports skin quality, recovery, and cellular repair
Side Effects
Common
- Injection site reactions (redness, swelling, pain)
- Mild joint stiffness or pain
- Peripheral oedema (swelling in hands/feet)
- Mild nausea
Less Common
- Headache
- Muscle pain
- Tingling or numbness in extremities
- Mild flu-like symptoms during initial use
Serious
- Elevated IGF-1 carries theoretical cancer risk — avoid with active or recent cancer
- May affect blood sugar — monitor in diabetic patients
- Not recommended during pregnancy
- Can cause fluid retention — caution with heart failure or kidney disease

FAQ
How does tesamorelin compare to CJC-1295?▼
Both are GHRH analogs that stimulate natural GH production. Tesamorelin has the advantage of formal regulatory approval and strong clinical data specifically for visceral fat reduction. CJC-1295 is dosed less frequently (daily vs weekly for the DAC version) and is typically combined with ipamorelin. Tesamorelin requires daily injection and is generally more expensive.
How long before I see fat loss results?▼
Visceral fat reduction typically becomes measurable after 8-12 weeks of consistent daily use. Clinical trials ran for 26 weeks to demonstrate full effects. Surface-level body composition changes take longer to become visually apparent.
Is tesamorelin only for HIV patients?▼
Its regulatory approval is specifically for HIV-associated lipodystrophy, but it is widely used off-label for visceral fat reduction and anti-aging by people without HIV. The mechanism of action — stimulating natural GH to target visceral fat — works regardless of HIV status.
