Tesamorelin is a stabilized growth-hormone-releasing peptide studied primarily in metabolic and visceral-fat research models. Its modified structure resists rapid breakdown, making it a distinctive tool among GHRH analogs.
What is Tesamorelin?
Tesamorelin is a stabilized analog of growth-hormone-releasing hormone (GHRH). A structural modification protects it from rapid enzymatic breakdown, so in research models it produces a more sustained signal than native GHRH.
Studied mechanisms (in-vitro and preclinical)
Like other GHRH analogs, Tesamorelin binds the GHRH receptor and prompts the pituitary to release growth hormone. In preclinical research it is most associated with visceral-fat and metabolic models, where GH-axis signaling is studied in the context of body composition.
Tesamorelin and related research peptides
Tesamorelin sits alongside Sermorelin and CJC-1295 as a GHRH-analog research tool, and is often contrasted with the ghrelin-mimetic Ipamorelin, which reaches growth hormone through a different receptor.
Quality and Certificate of Analysis
Every batch is analyzed by an independent, ISO/IEC 17025-accredited laboratory and ships with its own Certificate of Analysis documenting identity and purity. The COA is batch-specific and available on the product page.
Storage and handling
Tesamorelin ships lyophilized. Store cold and away from light, reconstitute with bacteriostatic water, and keep the reconstituted vial refrigerated.
Frequently asked questions
What is Tesamorelin used for in research?
It is studied as a stabilized GHRH-receptor agonist, most often in metabolic and visceral-fat research models.
How is Tesamorelin different from Sermorelin?
Both are GHRH analogs, but Tesamorelin’s structure is stabilized against breakdown, giving a more sustained research signal than short-acting Sermorelin.
Is Tesamorelin approved for human use?
No. It is intended solely for in-vitro laboratory research and is not for human or veterinary use.
How should Tesamorelin be stored?
Keep the lyophilized vial cold and out of light; once reconstituted, keep it refrigerated.
