    Labeled VAT reduction in HIV lipodystrophy. Ceiling 9 for approval; haircut because that label is not a gym visceral-fat protocol and a 2 mg cake is not Egrifta.

How it works

Tesamorelin is a synthetic analog of GHRH(1-44) with a trans-3-hexenoic acid modification at the N-terminal for enhanced stability. It is the only FDA-approved GHRH analog (Egrifta), approved for HIV-associated lipodystrophy (excess visceral and truncal fat).

Tesamorelin binds GHRH receptors in the pituitary, stimulating pulsatile Growth Hormone release. Unlike exogenous GH, it preserves the natural pulsatile GH rhythm and hypothalamic feedback loop. VAT reduction is the labeled HIV-lipodystrophy story. Do not generalize that into a fatty-liver or cognition drug for unselected adults.

Background & History

Tesamorelin (Egrifta) is an FDA-approved GHRH analog for HIV-associated lipodystrophy. VAT reduction is that label. It is not a general-population fatty-liver cure and not weekly CJC-1295.

Research Use Cases

  • ✓Egrifta identity vs CJC-1295 vs sermorelin
  • ✓Why HIV-lipodystrophy VAT math does not become a research-chem cut protocol
  • ✓Not a NAFLD or MCI treatment page

Dosing

PhaseDoseFrequencyNotes
FDA-Approved (Lipodystrophy)2 mgDaily SC injectionFDA-approved dose for HIV-associated lipodystrophy. Clinically proven reduction in VAT.
Longevity / Body Composition1 - 2 mgDaily SC injectionOff-label use for visceral fat reduction and GH optimization. Often cycled to minimize IGF-1 elevation.

Administration

Route / form
Subcutaneous injection
Timing
Once daily, preferably at bedtime on an empty stomach.
Empty stomach?
Yes - Empty stomach (typical for this injectable class).

Timeline

Week 1-4
Increased GH pulse amplitude. Improved sleep quality and recovery.
Month 2-6
Measurable reduction in visceral adipose tissue (VAT). Improved body composition.
Month 6+
Sustained VAT reduction. Cognitive and cardiovascular marker improvements in clinical studies.

Who it is for

Visceral Fat / Lipodystrophy

High

FDA-approved for HIV lipodystrophy. RCT data shows 15-20% VAT reduction in 26 weeks.

GH Optimization / Body Composition

Moderate

Off-label use. Preserves pulsatile GH rhythm vs. exogenous GH. Favorable safety profile.

Cognitive Enhancement

Moderate

Clinical studies show improved cognitive function in older adults with abdominal obesity.

Reconstitution

2 mg (Egrifta-style fill)2.0 mL sterile/BAC per product1 mg/mL2 mg = 2.0 mL = entire 2 mg vial. Follow the labeled diluent, not a BPC chart.

Safety & Considerations

FDA-approved (Egrifta). Generally well-tolerated. Injection site reactions are common. Monitor IGF-1 levels - discontinue if levels exceed normal range. Contraindicated in active malignancy or hypersensitivity.

Regulatory & Legal Status

FDA Status (US)
Approved

FDA-approved as Egrifta® for HIV-associated lipodystrophy

WADA Status (2026)
Prohibited (S2)

Competitive athletes subject to anti-doping controls should not use Tesamorelin.

Limits of current evidence

  • Egrifta 2 mg daily is the labeled job. Off-label “longevity” 1–2 mg is not that trial.
  • Cognitive and lipid papers in HIV cohorts are not a cognition indication for everyone.
  • This site will not treat HIV lipodystrophy or NAFLD from a peptide page.

Verdict

Tesamorelin is Egrifta, the GHRH analog with a US lipodystrophy label. VAT data is HIV-clinic data. It is not a general-population fatty-liver cure and not weekly CJC-1295.

Interactions & Contraindications

Glucose/IGF-1 watching. Active malignancy contraindication class. Labeled job is HIV-associated VAT, not wellness GH.

Synergies & Common Stacks

GHRH plus GHRP is the same receptor story as Mod GRF + ipa. Not a labeled Egrifta combination.

Tesamorelin vs. Sermorelin

Canonical comparison: Tesamorelin vs Sermorelin

AttributeTesamorelinSermorelin
FDA StatusFDA-approved (Egrifta® - HIV lipodystrophy)Not FDA-approved (was revoked)
Half-Life~26 minutes~11–13 minutes
PotencyStronger - engineered GHRH analogModerate - native GHRH fragment

Verdict: Tesamorelin is the clinically superior GHRH analog with proven visceral fat reduction and FDA medical validation. For users specifically targeting body composition and clinical evidence, tesamorelin is the preferred choice.

Frequently Asked Questions

What makes tesamorelin different from CJC-1295?▼
Both are GHRH analogs but tesamorelin is the full GHRH(1-44) sequence with an added modification, making it FDA-approved with extensive clinical data. CJC-1295 (with DAC) has a much longer half-life due to albumin binding but lacks FDA approval and clinical trial record.
How does tesamorelin reduce visceral fat?▼
By stimulating pulsatile GH release, tesamorelin increases lipolysis (fat breakdown) specifically in visceral adipose tissue, which is highly GH-sensitive. Clinical trials show 15-20% reduction in VAT after 6 months of daily use.
