Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH), consisting of 44 amino acids, designed to stimulate the secretion of endogenous growth hormone (GH) from the pituitary gland. It is primarily used in research settings to study the effects of growth hormone secretion, particularly in the context of fat metabolism, visceral fat reduction, and endocrine regulation. Tesamorelin is often used to investigate the GH axis, metabolic disorders, and age-related decline in hormone levels.

Tesamorelin is typically provided as a lyophilized (freeze-dried) powder, which requires reconstitution with sterile water or bacteriostatic water before use in research experiments. The purity of Tesamorelin is usually >99%, verified through HPLC (High-Performance Liquid Chromatography) or Mass Spectrometry (MS), ensuring its high quality for laboratory applications.

For storage, Tesamorelin should be kept in a cool, dry place and stored at -20°C or lower if unopened. Once reconstituted, it should be stored in a refrigerator (2°C to 8°C) and used within a few weeks to maintain its stability. It is critical to avoid repeated freeze/thaw cycles after reconstitution, as this can degrade the peptide.

Each batch of Tesamorelin is accompanied by a Certificate of Analysis (COA), which confirms the product’s purity, identity, and molecular weight, as well as providing storage recommendations and batch numbers for traceability and quality assurance.

Tesamorelin is intended for research purposes only and is not FDA-approved for clinical use. It is commonly employed in research on obesity, growth hormone therapy, and endocrinology, particularly in relation to its effects on fat distribution and body composition.
