🧬 Tesamorelin Peptide: High-Purity GHRH Analogue for Advanced Research;
Tesamorelin peptide is a synthetic version of the natural Growth Hormone–Releasing Hormone (GHRH), consisting of 44 amino acids. It was developed to help researchers study how growth hormone functions and regulates metabolism in biological systems.
Because of its high stability and purity, Tesamorelin is one of the most popular peptides used in metabolic, endocrine, and aging research today.
🧠 What Is Tesamorelin Peptide?
Tesamorelin mimics the natural GHRH produced in the brain’s hypothalamus. When introduced in laboratory models, it binds to receptors in the pituitary gland, stimulating the secretion of growth hormone (GH).
Researchers use Tesamorelin to better understand how GH influences processes such as:
-
Cellular growth and regeneration
-
Lipid metabolism
-
Energy balance and muscle composition
-
Endocrine system regulation
