Tesamorelin (Research Peptide)
For Research Use Only – Not for Human Consumption, Diagnostic, or Therapeutic Use. Tesamorelin is provided strictly for laboratory and scientific research applications, such as in vitro and in vivo studies exploring the growth hormone-releasing hormone (GHRH) axis, metabolic regulation, body composition, and adiposity models. All information below is for educational and research reference only and does not constitute medical advice.
What Is Tesamorelin?
Tesamorelin is a synthetic 44-amino acid peptide analogue of human growth hormone-releasing hormone (GHRH, also known as GRF 1-44). It features an N-terminal modification with a trans-3-hexenoyl group, which enhances its stability against enzymatic degradation compared to native GHRH. It is typically supplied as a lyophilized powder (acetate salt form) for reconstitution in research settings.
Mechanism of Action (Research Context)
In laboratory models, tesamorelin acts as a selective agonist at GHRH receptors on somatotroph cells in the anterior pituitary gland. This binding stimulates the pulsatile release of endogenous growth hormone (GH). Elevated GH levels subsequently increase production of insulin-like growth factor-1 (IGF-1) in the liver and other tissues.
Unlike direct GH administration, this upstream stimulation follows the body’s natural regulatory feedback loops, which researchers study for potential advantages in metabolic signaling, lipolysis (fat breakdown), and anabolic processes. Research focuses on how this pathway preferentially targets visceral adipose tissue (deep abdominal fat) while sparing subcutaneous fat in certain models.
Why Researchers Choose Tesamorelin
Tesamorelin stands out among GHRH analogues for its documented selectivity toward visceral fat metabolism in controlled trials, making it a valuable tool for studying:
Targeted lipolysis
GH-axis modulation
Body recomposition without generalized weight loss
Metabolic health markers in lipodystrophy or adiposity models
Storage for Research: Lyophilized powder is stable at –20°C. Reconstituted solutions should be used promptly per standard peptide handling protocols (typically with bacteriostatic water).
If you are a researcher investigating the GHRH pathway, visceral adiposity, or related metabolic processes, tesamorelin offers a well-characterized peptide with a robust body of published data. Always follow your institution’s guidelines and applicable regulations for research use.
