What is Tesamorelin?

Tesamorelin (Tesamorelin) is a research compound studied in metabolic. A stabilized GHRH analog clinically approved for HIV-lipodystrophy. Studied for its selective effect on visceral adipose tissue.

Overview

Tesamorelin is a synthetic GHRH analog with a trans-3-hexenoic acid protecting group that extends its half-life. It’s the only GHRH analog with FDA approval — for HIV-associated lipodystrophy, specifically because of its selectivity for visceral adipose tissue reduction. What makes tesamorelin notable in metabolic research: it reduces visceral adipose tissue (VAT) by 15–20% in published trials without shifting subcutaneous fat, total body weight, or insulin sensitivity significantly. That VAT-specific effect is rare and makes tesamorelin a valuable tool for isolating visceral-fat pharmacology. IF the research question involves visceral-adipose-tissue pharmacology or GHRH-axis modulation in metabolic syndrome, THEN tesamorelin is the GHRH analog with clinical-grade endpoint data. SO it belongs in NAFLD, metabolic syndrome, and HIV-lipodystrophy research. Lyophilized, ≥99% HPLC.

Research areas

  • Visceral fat reduction

    <p>Selective reduction in VAT with preservation of subcutaneous fat and lean mass. The mechanism differentiates it from general GH-axis stimulation.</p>

  • Clinical-grade evidence

    <p>FDA-approved for HIV-lipodystrophy (Egrifta). Multi-year cohort data supports sustained VAT reduction with continued administration.</p>

  • NAFLD research

    <p>Published trials report reduced hepatic steatosis in NAFLD cohorts — an off-label research focus given the VAT/liver-fat metabolic coupling.</p>

  • Administration

    <p>Daily subcutaneous injection in the abdomen. Standard research protocol is 2 mg/day for 6+ months to reach plateau VAT reduction.</p>

Storage & handling

Lyophilized Tesamorelinis stored at –20 °C protected from light. Once reconstituted with bacteriostatic water, store at 2–8 °C and use within 30 days for maximum stability.
